Windows 10: BIOS reads "Boot error" after cloning OS drive
BIOS reads "Boot error" after cloning OS drive
I just purchased a 1TB Samsung 850 EVO SSD to replace my 1TB WD HDD. I cloned my Win10 OS drive using Macrium Reflect, as I have successfully done countless times in the past from HDD to HDD, HDD to SSD, and so on..
When attempting to boot from either the SSD or HDD -with one or the other, or both connected to the mob- the BIOS reads "Boot error". Hitting any key will reboot the PC. I've tried startup repair with a Win10 repair disc and System Restore gives an error reading, "To use System Restore, you must specify which Windows installation to restore. Restart this computer, select an operating system, and then select System Restore., no matter which drive I try booting from.
I am at a loss and cannot decide what my next step is, I really hope I am missing something..
Have you tried clearing the CMOS? Changing drives often causes conflicts with stored info in CMOS.
I have reset the CMOS by removing the mobo battery. Haven't tried via BIOS settings.
You can try with only SSD connected. Boot up the PC with the Macrium Rescue disk then click on the option"Fix Windows boot problems"
Is the SSD the correct partition scheme type, GPT or MBR? GPT is for UEFI bios and MBR is for legacy bios.
I didn't create a rescue disc and my only other currently working machine is a 2015 MacBook Pro; no optical drive. I'm not sure of the partition type but I have tried booting in both legacy and UEFI. I did get Windows to boot once off the HDD before it eventually blue screened and saw that the SSD had less data on it than the HDD. I'm guessing Macrium didn't clone the drive properly. But I'm still stumped as to why the original OS drive won't boot.
You may need to insert your installation DVD and do a startup repair. I cloned a drive before, and for some reason the cloned drive wasn't set as an active drive. Once I did the startup repair, it worked, however, that was on Windows 7 when I did that
I've tried startup repair with a repair disc and it gave me an error, see op. But I think you're right, it may need to be an install disc. That's what I've used in the past when cloning drives. I have a Win10 .iso on my HDD, I'll have to try creating a live USB drive to burn the .iso to a disc when I get home.
When cloning a disk to another disk, sometimes the disk ID is also cloned causing conflict that 2 disks are having the same disk ID. That's why it's always better to create a backup image then restore to second disk, cluster size will be properly aligned and Macrium also performs trimming on the SSD.
You can download the rescue disk ISO from my G Drive and put on a USB to boot up.
You might have failed to copy the boot partition when you copied the drive... I always copy the whole drive vs just the system partition. Windows 10 creates some "reserved" partitions. In some cases, if you had multiple drives, the boot partition might not even be on the same drive, it's that way on my Windows 8 machine. :/
So my C: Drive has been acting up lately, with barely enough space to stay alive. I tried to take some space off the D: Drive, which has 240 GB of unused space, and add it to the C: Drive using Disk Management. But when I shrink the D: Drive and...
Just installed Win 10 pro on a new SSD, so a clean install. Started installing all my programs etc. Everything seems to be running well, except on thing that is annoying...
I have placed a few icons on the desktop via right clicking...
I know there are a handful of threads with the above error message and code, but I have yet to see a thread with what was my reason for the error code. I wanted to pass on what I discovered and how I fixed it.
I started with a standard Windows 7...
I have upgraded 5 machines and clean installed 3 machines.
Experienced an issue with one machine with continuous corruption problems
After the 3rd attempt I discovered that even with a Clean Install of Win 10 I get unrepairable errors - Sorry...
when restarting my laptop after a windows 10 update yesterday, got an " unmountable boot volume" message on start up with windows trying to repair but then goes to a black screen with nothing but a white cursor. only displaying black screen....
