MSConfig Boot - Can Only Boot In Safe Mode
Sep 29, 2015
Over the weekend I upgraded from 8.1 (which was working perfectly) to Windows 10. Unfortunately, it had a few problems - namely that it would 'hang' at random intervals (5 minutes to 5+ hours). In an attempt to isolate what was causing this, I was advised to use Msconfig to do a clean boot.
Unfortunately, in the process, I have rendered my PC near-useless, as I accidentally ticked the box "Use original boot configuration" under Selective startup. (I know, I know. I'm so cross with myself.) As a result, I am now presented with what looks like my old boot screen - offering Windows 7, Windows 8, Windows 8.1, Windows 8.1 with Media Center, but no Windows 10.
(I originally had Windows 7 on what is now my D: drive. I ended up dual booting with this and Windows 8, but I'm pretty sure the version of 8.1 - which I've just upgraded to Windows 10 - was a clean install. It's certainly on my SSD (C: drive).)
Anyway, by using Change defaults... - Choose other options - Troubleshoot - Start-up Settings, I was at least able to bring up the screen that gives you Safe Mode as an option. This allowed me to boot into Windows 10 Safe Mode.
I went back to MSConfig and eventually found a way to deselect 'Use original boot configuration' (it was greyed out for a while). However, on restart, it still showed me the old options, i.e. no sign of Windows 10 Pro. It seems the only way I can currently boot into Windows 10 is via Safe Mode.
I've tried various things today - I tried to use Bcdedit to force it to look at the C: not D: drive, and I've tried booting with a Windows 10 DVD and using the Repair option (but partway into the repair process it starts thinking it's a Windows 8 machine again...).
I've just 'spoken' to a chap at Microsoft and he is adamant that there's no alternative (because there's no Refresh option under Settings - Update & Security - Recovery) but to reinstall Windows 8.0, and then upgrade to 8.1 and then Windows 10. As you can imagine, I really, really don't want to go down that route. But, at the moment, I can't even roll back to 8.1.
Given that I can still - sort of - boot into Windows 10, the correct MBR/BCD/whatever must still be on my C: drive somewhere, surely?

In my desktop I have two hard disks ( disk 0 and disk 1 ) . Disk 1 is a clone of disk 0 created by Macrium Reflect
Disk 0 : ( C: ) windows 10 pro , upgrade from windows 7 , ( E: ) windows 8.1 pro , ( G: ) Storage partition
Disk 1 : clone of disk 0
problem description : I see in msconfig / boot a wrong listing
windows 10 ( C:WINDOWS) : Current OS ; Default OS
windows 8.1 pro ( H:WINDOWS ) instead of ( E:WINDOWS )
Nevertheless the dual booting works fine as well as the shift between the disks via BIOS.
The question is , could I fix the situation using the EasyBCD of Neosmart Technologies to edit the bootloader ?
I see can change drive letter H: to E: and save the change , am I right or wrong ? or any other way ....

Is there a way to boot into Win 10 in a safe mode? The reason I ask is I am having trouble in normal mode trying to get rid of my win.old file. It will let me delete some of it but not all. So maybe in safe mode I can delete it all or am I missing something here?

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.

Upon attempting to perform a fresh install of my display drivers using DDU, I somehow managed to permanently blue screen Windows 10 (Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED). So every time I try to boot into my OS, I get a constant blue screen of death, resulting in my computer to continuously restart and blue screen.
So now I'm trying to boot into safe mode from a cold boot, is there a way that I can access Advanced Options without requiring to boot into the OS itself?I'd like to create a recovery disk with a flashdrive, but I do not have an alternate computer that runs Windows 10, just a MacBook Pro

I have a Lenovo laptop upgraded to Windows 10. Last night I switched it off but now when I turn it on, it stucks in the startup Lenovo logo. I think that it is a driver issue but I cannot boot it in safe mode to fix it? What can I do? ( I don't mind to lose my files).

1. If I try to select normal startup in msconfig.exe, it doesn't stick; always reverts to selective startup.
2. When I boot to the Windows 10 desktop, it always opens a Windows Explorer window at /windows/system/ which shows only a Speech folder in the right panel.
3. Checking my BootManager using BCDEdit, I see this but I don't understand what the entries mean or whether any of them are connected to the problems 1 and/or 2:
Code:
C:Windowssystem32>bcdeditWindows Boot Manager--------------------identifier {bootmgr}

Currently, I have dual boot Win7 and Win10. And the only reason I have Win7 is because the drivers for a printer were not updated to Win10. Now recently HP did just that, and I no longer need Win7.
The way I have it set up is that I have Win7 on one partition, Win10 on another (100GB each) and the rest is Storage. Is it safe to simply remove and format the partition that has Win7 on it ?

I have upgraded Win 8.1 Ent into Win 10 Enterprise. While upgrading I had an older version of BIOS. Since then I have upgraded to the latest BIOS version available for my MOBO. My MOBO is ASUS's P8H77.
I can not boot or restart into BIOS from Win 10. I have googled the problem and it was mentioned something about new UEFI method of OS installation. When I am trying to restart/boot using the Advanced Boot option my OS is missing the "UEFI Firmware Settings" option, therefore I can't get into my BIOS.
My questions are:
- All this is happening because I had an old version of BIOS and when I upgraded something got screwed up?
- Does my motherboard support Win 10 UEFI option at all?
- Do I need to do clean install? Is it possible to avoid such option?
Reason for all these trouble: My PC freezes when I leave it working overnight. I do not know how to troubleshoot it because no reason for the freeze is indicated in the Even Viewer. Why the heck my PC freezes? I do not get any BSOD or errors, just a freeze and the only way to reset the PC is to hold down the power button.

So at first, I was trying to resolve an issue with my BD-ROM drive described here: XPS 8700 - BD-ROM (HL-DT-ST DVDRW/BDROM CH20N) Not Recognized Windows 10 - Disk Drives (HDD, CD/DVD, Blu-ray) Forum - Disk Drives - Dell Community
However, when attempting to try different things, I am now in a position where I can no longer boot to Windows 10. More specifically, when I turn on my computer, I get an error saying no bootable drives found and it just lists my SATA 1, 2, 3, etc. drives with an option to restart or go to BIOS setup. In other words, I don't even see Windows anymore existing.
My basic computer specs:
Dell XPS 8700 SE
Intel Core i7-4700
Windows 10 with 1511 update
2TB hdd with 32GB mSATA SSD cache drive
16GB RAM
BD-ROM
I need to get Windows working again, and hopefully, get back my data. Here's what I did to cause the problems:
1) I went to Dell UEFI BIOS setup, and changed the SATA mode from "RAID" to "AHCI". Saved and exited BIOS.
2) After rebooting, Windows failed to load, had a consistent blue screen with the sad smiley face with error "IO1_INITIALIZATION_FAILED", automatic repair also failed.
3) I tried reverting back to "RAID" in SATA mode in BIOS, but it failed to change anything. Windows still wouldn't boot
4) I then entered into the special BIOS menu showing devices which listed my mSATA cache drive and hard drive and RAID settings. Since it showed that the cache drive was "Disabled", I thought I could fix my issues by re-creating the RAID array.
5) I tried to delete the current RAID setup shown in that BIOS menu, then chose the option to recreate the RAID0 array by selecting the option to create a "Striped Disk Array".
6) Once I did the above, Windows itself disappeared, and trying to undo the RAID0 option did not fix anything
So now I am no longer seeing Windows, not sure if my data on the hard drive still exists, and my cache drive (obviously) is not working.
doing a clean reinstall and losing all my previous data in Windows?

Okay, so the other week i received a new Clevo P650SE laptop. The laptop only had a 500GB 7200RPM HDD with Windows 10 to begin with, so yesterday i added my Samsung 840 EVO SSD. As i wanted this to now be the primary drive, i made another new installation of Windows onto here. After doing this, the system now displayed a boot selection at startup with the choice between the new Windows 10 installation on my SSD or the old one on the HDD.
As i no longer wanted to use the HDD for running Windows, i decided it would be best to delete Windows from this drive. So i booted onto an Ubuntu USB and wiped the entire drive of it's data in GParted, which included three different partitions. This seemed perfectly fine to me at the time, because i had a the new installation from the SSD showing up in the boot manager.
However, when i rebooted the machine and attempted to boot into the new installation on the SSD, it gives me this message:
"The boot configuration data from your PC is missing or contains errors.
File: /EFI/Microsoft/Boot/BC Error code: 0xc000000f"
I have tried everything to recover the system but nothing has worked. Startup repair from my Windows USB doesn't do anything, the system reset wouldn't operate because it stated that the partition was locked.
Nothing with the Command Prompt is working, I have done 'bootrec /fixmbr', 'bootrec /fixboot' and 'bootrec /rebuildbcd', but the last command returns the following error:
"The requested system drive cannot be found."
I also did 'bcdboot C:/Windows' but that also refused to work. I assumed the reason for this might be because the drive didn't have a letter, but when i attempted to add a letter is says:
"The specified drive letter is not free to be assigned."
Both drives in my laptop have now been completely wiped and converted to MBR, but even with the two drives empty the original message still appears when booting my Windows USB in UEFI.
I have only had this laptop a couple of weeks and it's already completely messed up. I can boot the Windows USB in Legacy and install Windows as normal, but of course i'm looking to have it back on UEFI as it was before.
