A while ago I bought my pc off ebay. It came with windows 8 already installed. The guy who sold it said that he built the pc and decided not to use it so he was selling it. I've upgraded to windows 8.1 and now to windows 10. How can I to check if my OS is OEM?
View 1 RepliesWhenever booting my pc I get a "operating system wasn't found error". I've checked to make sure my hard drive was set to the boot drive and I've tried reinstalling but that doesn't work either.

View 1 RepliesSo I upgraded to Windows 10 last week, & after a few days decided I wanted to do the reset feature to have a nice clean install. I was also getting an annoying pop-up error that looked like some sort of malware, but virus & malware scans weren't getting rid of it.
Ok, so I do the reset, & opted for full clean not the quick one, just to make sure I got everything off there. It took quite a long time ( about 15-20 minutes per 1% progress), so I left it & came back later. When I got back I had an error message that said "There was a problem resetting your PC." with my only option being to click cancel. So I did. after that it brought me back to a reset screen, where I attempted to do the quick reset a few times, & it failed after a few percent each time.
At this point I decided to shut down & try again. When I booted back up I was greeted with the lovely message of "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Crtl+Alt+Del to restart"...so my pc was wiped but the reinstall part failed somehow it seems, leaving me with nothing.
I created a bootable usb for Win10 from the Microsoft website, following their instructions to the letter. Installation seems to go fine ( Copying Windows files, Getting files ready for Installation etc). That screen finishes up & I get a Restarting in 10 Seconds screen. I let it restart & then I get stuck at a black screen with a blinking cursor in the top left corner.
I have done some reading on this & tried everything I found, nothing has worked. I've let it sit, tried hitting Crtl to type password then hit Enter, I've unplugged my second monitor & any non essential USB devices, everything. I've tried installing multiple times, to the same result.
Also worth noting that I was unable to revert back to Win7. When I put my 7disc in I get a message saying "A required CD/DVD drive device driver is missing. If you have a driver floppy disk CD,DVD or USB flash drive, please insert it now."
I've used this disc many times with no issue, & now I can't even reinstall 7?
downloaded windows 10 - 32bit instead of 64.Im just downloading the 64 bit now and burning to a disc will my laptop let me go back up to 64 even tho its current system is a 32?The laptop originally was windows 8 64 bit But can something that's gone down to 32 be put up to 64l
View 1 RepliesMy dell 7500 has windows 7(C: drive) and windows 10(F: drive) installed on the single internal HDD. It also has three USB disks used only for data. When I boot I get a message saying that an operating system cannot be found and I should try unplugging my USB drives and then reboot. When I unplug the USB drives and re boot, it finds the windows systems and finishes the boot process with no trouble.
Checking the BIOS shows only the CD-Rom drive and the three USB drives are listed in the boot order and the drive listing. I then deactivated the "boot from USB drives" item in my BIOS and then the computer boots fine.
Also, I have been experimenting with Ubuntu on a USB pen drive but have removed it. I suspect that there are some parts of grub hanging around.
I am looking forward to replace my laptop HDD with a SSD. My laptop is the Toshiba Satellite l70 pro 17.3". I have a basic idea of doing transferring windows 8 to an SSD but apparently it is harder to transfer Windows 10 to a SSD when compared to Windows 8 and 7.
View 9 RepliesNot sure what to do. I did find a page to uninstall Win 10, but I'm not sure it would do it correctly without the internet. I'm not even sure if it would work because I was afraid to try it. It is a HP computer and it was running on 8.1. I'm using my spouse's computer to post this.
View 4 RepliesI used the Windows 10 rest pc feature and selected the options to delete everything off of my drives. There was a problem during the installation and I clicked the option to boot back into windows 10. The laptop just boots into the MSI splash screen over and over again.

View 1 RepliesMy Acer Aspire One was upgraded to Windows 10. Eventually, I ran into some issues with the start menu not popping up, so I decided to run a clean reset of Windows 10. The reset failed, so I turned off the notebook. When I turned it back on, the message "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart," popped up. My first option was to try to use either f2 or f12 to see if there was some way to get around the issue, but then I remembered that, recently, my notebook had stopped responding to those commands. I do have a USB Logitech K120 keyboard hooked up to it (since the original keyboard messed up,) but it had been working fine for those commands and such up until now.
Today, I downloaded Win 10 using the Media Creation Tool in an attempt to create a bootable USB drive. I plugged that in, yet it doesn't seem to recognize it at all. The same message pops up as before. My acer doesn't have a CD-ROM or anything of the sort, so the USB appears to be my only hope. Is there anything that I can do? I'm hoping there's a way I can force the notebook to recognize the USB, or at least boot into the f2 or f12 commands to see if I can use them in any way.
My laptop (as listed in system specs) will not power up and if it does it says no operating system.
View 2 RepliesWhen upgrading from Windows 7 to Windows 10, am I able to choose what drive I would like Windows 10 installed to if I have multiple drives? I want to put an ssd in for the operating system when I upgrade and would I be able to just tell Windows 10 to install to the ssd?
View 1 Repliesso a while back when the Windows 10 Upgrade had popped up on my computer, I upgraded with no problem at all. I wanted to do a factory restore in order to clean up my laptop completely, however while updating, the power went out and the computer shut off. Logging back on, I couldn't access Windows at all. I couldn't even get to the login screen. The message that had popped up had said that no operating system was found and to press Ctrl+Alt+Del to restart. I have a Lenovo ThinkPad T520.
View 9 RepliesI recently upgraded my windows 7 to windows 10. I have had everything activate properly. I then decided to do a fresh install of windows 10. I loaded boot media on my pc and everything went fine. Now with the fresh install of windows 10, at boot up, I get the option to choose windows 10 or windows 7. How to I change this so it ALWAYS defaults and boots windows 10? Considering I wiped my hard drive clean windows 7 shouldn't even be an option.
View 4 RepliesI upgraded from windows 7 to 10 about 2 weeks ago, absolutely no issues, i was happy with everything.
My computer had froze and i forced a shut down via power button. Upon starting again i was greeted with "no operating system found"
I fixed that problem now im greeted with a black screen with something like "no bootable device found please detach any devices"
What i have tried is....
Made a win10 usb with the media creation tool from another computer.
Startup repair does not work, error is "the hard drive is locked"
I have tried with the command prompt the following commands
Bootrec /fixboot
Bootrec /fixmbr
Bootrev /rebuildbcd
*rebuildbcd tells me i have 2 installed windows os. One is regular windows and windows.old*
(If i say Yes to rebuild both of those, my media creation usb stops working if i restart. I get the error 0xc00000f and have to recreate the media creation tool on the usb. Otherwise i keep getting the same error)
I have also tried different sata ports on my motherboard, resetting bios settings, changing boot order, changed sata cable. What else can i do?
one part before installing Windows 10. In creating a virtualbox you will see three lines with the top to fill in with name " Windows 10 Technical Preview " then second line with type --Microsoft Windows and the last one with version -- I wasn't sure which to pick the right operating system of my laptop. Well I do know that my operating system is Windows 7 Home Premium SP-1 64X but see several youtube videos show with Windows 8.1. Am I click with Windows 7.1 in the line. Is that correct.
View 4 RepliesRecently, I purchased a Microsoft Surface 3. From the day I got the tablet, it has been having freezing problems that seem to progressively get worse and worse. Today, I couldn't go two minutes on my Surface without having to restart it.
I would prefer to return the product, but since I can't, I decided to first try to update it. The update kept getting frozen, encountered an error or would just be stuck at 0%.
After exhausting all the other options I knew off, I quickly moved what little files that I had off of my tablet and then performed a factory reset.
The factory reset got stuck at 99%. And I don't mean that it just was there for a few hours--no, the screen literally froze. So I restarted the tablet again, which brought me to a screen that says, "Choose an Operating System" that has two options. Both options are "Windows 10 on volume 3." There seems to be no distinction between them. But the problem is that if I click one, and it doesn't matter which one, or if I just let the tablet automatically run on one of them, it loads for a few seconds with the "Surface" screen, and then immediately loops back to the same "Choose an Operating System."
I have a laptop that was a Windows 7 Home Premium machine (HP dv6-2150us) that had an Windows 10 in place update performed on it a few months back (Nov 5, 2015). It had been running fine but recently had been randomly crashing. Two days ago, it crashed again and would boot to the "Startup Repair" mode attempt to run, then tell me "Startup Repair" couldn't repair your PC. and endlessly loop through that (if you told it to reboot) unless I went the Advanced Options.
I tried accessing Safe mode with and without networking, but not luck. I can get to the command prompt.
At one point it out of the blue it displayed the path to the "SrtTrail.txt" file which apparently is the log train for the "Startup Repair". The screwing thing is I check the date/time on the log file and each time the "Startup Repair" runs it does update the file whether it displays it on the screen. So apparently it could be random whether MS lets you know where to look for clues. Yeah MS!
Any way the I looked at the "SrtTrail.txt" and it states that the following pass.
"Check for Updates"
"System Disk Test" "
Disk Failure Diagnosis"
"Disk Metadata Test"
"Target OS Test"
"Volume Content Check"
and the Root cause found "The operating system variation is incompatible with Startup Repair"
I did a bit of Googling and found others with the same problem : [URL] .... But they did not have success in reviving the Machine
Any way of resolving the issue that would leave my programs intact? Is it as simple of having the correct BCD entry? If so, what the BCD entry should be the entry for a Windows 7 box that had a Windows 10 in place upgrade done?
The current entry in the boot record is
osdevice: partition=E:
Systemroot: windows
resumeobject: {3c5d113c-777-11e5-82d9-8199ff9a6bfc}
