BSOD Saying Unmountable Boot Volume
Aug 20, 2015
After upgrading to Windows 10 from Windows 7 within the last week, everything was fine at first. Then this morning Everything on screen froze, and when I did a force restart, the following happened (and continues to happen ad nauseam):
Windows tries to boot as normal, but I get the BSOD saying Unmountable_Boot_Volume
It then restarts, saying it's going to repair the problem, only this time it flashes to a blue screen that says Chose Your Keyboard Layout. At this point I am unable to use either my mouse or keyboard. I've tried wireless, wired, all USB ports. Nothing.
I don't have Windows 7 disc (came pre-loaded from the factory), and I don't have a Windows 10 disc or flash drive. The only other computer I have to work with this is an old laptop running XP. I downloaded the Media Creation Tool, but when I try and run it on my XP laptop it says it's not a valid win32 application, so making a flash drive boot seems out of the question.

My original os is win7 then i upgraded to 10... After a while of using it... It opens the Blue screen saying unmountable boot volume.. Also i dont have win7 cd since the os was built in...
Next i rebooted it, it says "preparing automatic repair" i tried to wait.. But after it says that, it goes to a black screen and nothing happens
Then i tried dloading the iso from the site and then burned it to a usb.. Then it says
Press any key to boot from USB
*presses any key*
BOOTMGR is missing
Press ctrl+alt+delete to restart
Is the problem in the usb or it just wont open because of the error?
I only have recovery disks on win7
My laptop is Vaio SVE111A11W
Cant open my laptop due to this so i cant really attach the needed files..

A week ago, I got a new ssd drive and used EaseUS ToDo Backup to clone my Win10 hdd to it. Windows actually worked great for a week on the ssd after this, but then I thought it would be safe to wipe the old hdd to use it for extra storage.
Now, if I try to boot the Win10 on the ssd, I get error messages about "unmountable boot volume". I've tried unplugging other harddrives to make sure they weren't interfering (they weren't), and I've tried using a Win10 install disc to both refresh and reset the Win10 ssd (both failed due to a missing partition).
I've used another computer to backup the Win10 ssd, so I'm okay with reinstalling, though I'm not sure about reactivation (I got this copy of windows as win7 from a used computer and upgraded it months ago, so I don't have the original box code.)

I was wondering whether it were possible to open the volume mixer instead of the volume control when left-clicking on the volume icon in the tray. At the moment I have it set to open the old classic menu, but not the volume mixer.

my game volume and my chat volume are mixed so that when I turn up my chat volume, my game volume also turns up. when I turn up my game volume, it doesn't turn it up, but when I turn up my chat volume, it turns up both my game and chat volume. How can I fix it so that my game volume and chat volume are different?

Last night I accidentally hit 'hibernate' and as i was in a rush i held the power button. Low and behold i woke up this morning went to put it on and got to the BSOD. I basically get to the login screen, login and then it repeats. Ive had the BSOD before but it just restarted and everything was fine. Now I'm trying to turn the pc on and its stuck in a reboot cycle, doesn't get to the login screen. I've literally tried everything, the PC won't even reset or anything. Genuinely stuck....

I've gotten the BOSD 7 times today. The BOSD said it was because of various things throughout the day, at first it said it was Memory Management, but after that I just started to get annoyed.
Checking back through the event logs, the bugcheck says the errors were: 0x00000050; 0x000000ef ; 0x0000001a; 0x0000000a; 0x00000139; 0x000000c1
If it isn't obvious, I really don't know how to solve this or if the bugcheck errors useful at all. What I do know is that I was just using google chrome when some of the crashes happened. Also during the day, several times I booted up my computer and logged in and then went away for 5 minutes after logging in (without doing anything). When I came back, it was obvious that my computer had restarted.

I am using Dell inspiron laptop (pretty old one) which started acting weirdly. Upon examining, there was a problem with HDD so I had it changed.
As soon as I got new HDD installed and installed Windows 10 on it, computer started acting weird again - slow startups, random freeze etc.- but it was running ok and I was fine with it. But earlier today, it suddenly displayed BSOD and crashed when it was idle. Now to the main and the funny part, it does not boot anymore. To elaborate, blank screen appears after BIOS screen (right when the logo of windows should be displayed) and it remains blank for several more minutes before the logo and spinning dots magically appear, it doesnt disappear thereafter.
I figured, I could run startup repair or some other tool to solve the problem by booting from the DVD of windows 10. Now for this one, the logo appears with the spinning dots which disappears after a while like it should. And after it disappears, blank screen persists thereafter. Dumbfounded, I tried booting from a USB stick of Windows 8 I had which gave the same problem.
I have already tried altering most of the options in BIOS and the diagnostic tool gives and all-ok for all the installed hardware.

I run Win10 under Parallels at MacBook. Few days ago it started to crash about 30 minutes after boot. I don't need to do anything, just wait and it will die. Usually it's REGISTRY_ERROR, but sometimes another error.
sfc shows some errors, but they don't look dangerous.
I've talked to Parallels guys and they claim it's Windows issue, not VM. Checked Win7 VM and works fine.

BSOD happens only when the computer cold boots from a prolonged inactive state. If the PC is off for several hours and is turned on it occurs. Computer typically blue screens, sometimes it freezes at the bios splash screen where they Windows 10 circular loading icon appears on this Gigabyte. I've seen multiple reasons for the occurrence such as bad pooler caller and irql not less or equal. The BSOD happens once then after the computer functions as normal with no other issues.
Power supply, graphics card, and SSD were both pulled from a previous build with zero issues in that build. New to this build is the motherboard, processor, and RAM.
Ran Memtest86 with no errors for 8 passes but I just realized it was after the initial cold boot BSOD and not going from the inactive state to the test directly. Will be swapping out the RAM at Microcenter today just to eliminate that possibility.
Windows 10 was a clean install but it happened on the previous install, BIOS is flashed to the most recent release.

I have bsods and game crashes of steam. I putted a new ram because the previous ram kit died (faulty rams causing bsods)and also I have a new graphic card r9 280 (because the previous gtx480 died too). What can I do? Bumps are not specific. I believed that sound driver causing problems and I disabled sound controller from bios and uninstalled the drivers. Unfortunately bsods don't stop. I have checked for drivers , updates, memtest but nothing. I noted that bsods and crashes happen in the first boot. If I have a bsod or I reboot after a game crash then BSODS and crashes stop to happen.

My Windows 10 (64bit) has always had issues with "page fault in nonpaged area" errors, usually when rebooting from sleep. Yesterday, my system crashed again again. Instead of booting up as normal, it crashed again with the same error, rebooted, and crashed again. My computer can no long boot to Windows.
I've searched online and have seen that it could be my RAM, so I tried running one stick at a time and it didn't work. I also tried to use a bootable flash drive (made with Media Creation Tool) to reformat my hard drive / reinstall Windows 10, but I get the same error/crash when I boot from the flash drive.
Here's my system specs:
CPU: Intel I-4790k
RAM: G.Skill RIPJAW 2x8GB
MOTHERBOARD: Asus Z97-A ATX LGA1150
STORAGE: Samsung 840 EVO 250GB SSD

I just recently upgraded from an earlier build of Windows 10 to the latest build 11099. That went okay. But the problem was when I decided to extend the system partition (as it had only 3GB free left), after rebooting to extend the partition with MiniTool Partition Wizard (it required me to reboot so it could unlock the partition). That seemed like it went okay too, but after restarting, I would get a BSOD and no boot up at all. It seems like the partition extension has messed up the boot files. I say that because a folder named "$WINDOWS.~BT" has been created in the root directory of the system drive. (Now it's drive G: because I'm on another system in another partition temporarily).
And some other folder as well:
So my question is this. Since I have all these boot files here, could it possibly be that while the partition was being extended, the software I used might have messed up those files, and now my Windows doesn't boot up?
If so, or whatever the reason for that matter, is there anything I can do to take those boot files back to where they belong?

it has given me several reasons for BSOD, such as: unexpected kernel mode trap security check failure and others...
I am running in safe mode now without problem for quite a while so I guess it is a driver problem, I hope?
here is my debug thing

Installed the latest video driver rebooted fine. Checked again for Windows updates. Found 2 critical updates. Installed rebooted, and has not stopped rebooting. The pc never shows anything on screen or gets to a place I can boot from disk. Switched HDs to go back to win7 but still the same. Cannot get anything on screen. Just constant boot.

As you could see the file which cause the bug is not very current (appid.sys), so i think it's not the real culprit... Of course i've tested memory, ssd, virus, before post here. I've also bought who crashed pro for analyse the dump and installed windbg but for the first, no essential information and for the second i don't have all knowledge for exploiting this tool throughly...

I have an HP pavilion dv7-1132nr which came with vista,and I upgraded to win7home edition no problems for years. I installed win10 download and every time I boot up it crashes within 5seconds shut the power off and on the second reboot it starts just fine and runs ok. I can restart with no problems but continue to have the crash from a dead start.My computer guy reformatted the drive and reinstalled win 10 from a install disc but the same problem still exists.

Asked my daughter to start my laptop. She said "The mouse isn't working," then we were hit with a BSOD. Hoping it's a one off, but just in case...

I recently installed Windows 10 from 8.1 on my HP pavilion laptop (I got it just over a year ago, not sure the exact model). All I did was go through the free upgrade process.
Everything seemed to work fine in the first 24 hours, but now I encounter a blue screen with grey lines when I try to boot. Eventually, after a few attempts (on its own) at rebooting, I get to the repair/restore screen. System restore hasn't worked in the few times I've attempted it, and I can only boot up in safe mode without networking.
I have no media disc for Windows 10 or anything like that, and I'm relatively inept in programming.

In order to force a safe mode start in Widows 10, I used the msconfig command in the Run Box. I clicked the "networking" radio button; unfortunately, that UNCLICKED the "minimal" radio button. Now I am unable to boot into anything. I have created a Repair / Recovery Disc from a similar PC, but it does not work with my HP ENVY.

I upgraded my laptop from Windows 7 to Windows 10 recently. About 90% of boots, my laptop will hang a and produce a BSOD. Initially, the BSODs were typically "system thread exception not handled" and "pfn list corrupt".
However, after the latest Win 10 update last week, initially everything went well, there were no boot hangs for awhile until a few days ago when it keeps on BSODing on boot with the error "Inaccessible boot device". The subsequent restart would end up with a BSOD of "system thread exception not handled". It works only after multiple restarts, which is worrying.

When turning on my computer today, I had to face a BSOD with the error name being "System Thread Exception not Handled", which prevented me from launching Windows 10 in either way. So I rebooted my computer on my Linux Mint partition in order to look on the internet the solution to this error. I then created a USB bootable with Windows 10, so I can access to the troubleshoot kits. However, when I launched my computer again on my USB key, I found myself in front of a black screen with words saying "Reboot and select proper boot device".
Things get quite weird from now, because when I try to boot from my SSD where Windows 10 is installed, I no more have the previous BSOD, but always and always this black screen with the same message. I do not know how to do now in order to access to Windows 10 again.
Unfortunately, being unable to access to Windows 10, I can't give you a DM Log Collector.

Every since I upgraded to windows 10 and boot my desktop machine I get a BSOD with Bad Pool header. It keeps looping and rebooting with the same error. The only way around it is to go into the bios and save changes and then it allows me to log in. I have disabled fast reboot and still no joy. Attached is a log file with all the relevant info

My Win10 laptop flips out on boot with a blue screen, right before/after you can see the mouse. It never reboots when it says it will. And it seems to blame my graphics card for this, as Catylitst Controll on logging claims that there is no AMD driver or thats its malfunctioning. I have to reinstall it to get my computer working better than a snail's pace, and for Catylist Controll to reconise it.Will get a dump of the error, just gotta restart a few times, as i accidently deleted the error dump and used disk cleaner.
Edit: Error is: , And the dump: W10LAPTOP-Sun_02_07_2016_134851_47.zip
