Question I need help with my ssd. mbr2gpt

[Charles Lalonde]

Im trying to convert my drive from mbr to gpt and it's not working.
Basically every time I run checkdisk it finds 0 errors, 0 bad sectors but everytime I check disk it says there an error...
I've used other software, finds 0 errors.
So I cant shrink the partition to proceed....

1. Why the conversion?
2. Give us the full parts list of this system.

When doing the mbr2gpt function, what specific error did it give you?

Delete recovery partition.

diskpart​

list disk​

select disk 1​

(select 447GB disk)​

list partition​

select partition 3​

(select 482MB partition)​

delete partition override​

exit​

Hmm, now when I do: mbr2gpt /convert /disk:1 /allowfullos

it says Cannot find OS partition(s) for disk 1

 

[SkyNetRising]

Did you delete 482MB partition? or some other partition?
Show Disk Management screenshot.

You may need to disable recovery environment or just reboot your pc.

reagentc /disable​

Try fixing bootloader. There might be some invalid entries after removal of recovery partition.
Execute from elevated command prompt.

bcdboot c:\windows​

Ok and after that I try mbr2gpt:
Trying to shrink the OS partition
Cannot find room for the EFI system partition.
Darn

Create another bootloader at the end of the drive and delete original 100MB bootloader.
Execute from elevated command prompt. Regular command prompt will give error on last step.

diskpart​

list disk​

select disk 1​

create partition primary size=150​

format fs=ntfs quick​

assign letter=H​

active​

exit​

bcdboot c:\windows /s H:​

Do not reboot, if there were errors. Show screenshot.

If there were no errors, then reboot.
Now partition at the end of drive should be marked as system,active.
Then delete 100mb partition at the beginning of the drive. Retry mbr2gpt after this.

[SkyNetRising]

Format command should have formatted it already.
Did you skip the format command?

[SkyNetRising]

yes im here.

Press cancel in that dialog box.
Continue with:

format fs=ntfs quick​

active​

exit​

bcdboot c:\windows /s H:​

If you exited diskpart, then delete H: partition and redo all the commands in post #19.

I feel like I should retry without missing that part...

 

[SkyNetRising]

Everything worked.
Now you have to reboot the pc.
Check and make sure, new 150MB partition is System, Active in Disk Management after reboot.
Then delete old 100MB bootloader and retry mbr2gpt.
