C Drive Has Moved!!

[Abdullatif]

Hello,

I'm using Windows 10, and I'm having trouble booting. I'm getting an error inaccessible boot device. After further investigation, I found out that my drive that has windows (C) has moved to another (F). I can access the CMD, but not sure where to go after there...

tried running repair?

Yes .. didn't help. Tried resetting BIOS which also didn't help, I tried checking the Nvm.2, nothing wrong with it. I would like a way to change the disk letter while in recovery mode. Currently, I'm not able to access Diskpart

use repair and boot into CMD and you should access diskpart.

I just assigned F to C, but didn't work like I expected unfortunately. I will try a couple of commnds fixMbr, and others to see if anything changes.

Is it MBR or GPT boot?

Hmm you are correct, I think it's a GPT not an MBR, is there a way to verify? 

[Robchil]

did you set the partition as active in diskpart?

I would have looked in bios at BOOT ORDER and set the drive with the C partition first. 

Then set to boot from that drive and no other drives

If you have multiple drives in the computer and another drive had windows previously, the boot loader from that partition may start instead and cause  issues.

I wrote select volume and then wrote my command to change the letter.

 

Side note: After i rebooted, the letter changed back to my original C drive became an F again.

I went to boot order, and it set not particularly to a drive letter, but to my device which is an Nvme. I got multiple hard disks

I don't know command line enough to tell the command. Perhaps you can make a bootable USB drive with some partitioning software, like Minitool Partition Wizard and boot from there?
Though if you can't there might be a BIOS option to set GPT priority besides the boot sequence. Like:

Spoiler

 

As I also had the problem, just had to swap boot order in the given menu, not just "FIXED BOOT ORDER"

Don't really know what the BBS Priorities mean, but it worked. 
You probably don't have same BIOS, but I'd suggest to search some boot settings in BIOS.

I will give it a try! Thank you.

I just realized Minitool free won't allow bootable USB rescue disks to be made.

AOMEI Partition Assistant allows to make a bootable "rescue USB" ... from there it's easy to check if the drive is MBR or GPT.

A couple of days ago, I had upgraded my pc. I installed a new NVME which is much better than the one I had which also had my windows installed. I migrated the OS to the new NVME, had no issues. This problem just popped, I don't know what the cause. I'm not sure if i should migrate my OS back to my old 960 nvme which has priority boot set just now. I think i should keep the new 980 Nvme just fot games just to avoid problems....hmm
