I’m very happy from your help video can made me fix my laptop mbr disk to gpt disk fail because my disk have more than 3 partitions

Thank you very much

I know it has been over a year but I need your help. I followed all your instructions to the letter but after making changes to the Bios, Windows failed to boot, the screen shows a "Boot Menu" shortly after start up. Please how can I fix that?

THANX BRO U HELP ME ALOT

Creative, I have to subscribe and watch all your videos for now

I can't boot to my bios to change these settings....so i forgot it?I cloned the disk c: but cloned mbr from mistake.

Hi sir, what to do if there is an "*" under Dynamic section in list disk option of cmd promt.. should i follow same steps??

But MBR2GPT wipes your entire drive, reformats it, so regardless you'd need to reinstall your operating system, I don't think I can risk this

there is 250mb unallocated logical partition that is becoming primary when i try to create. i think it is not allowing to convert mbr to gpt.
i had converted mbr to gpt long ago but few days ago i changed it back to mbr but due to some limitation to mbr i am trying to convert back to gpt. but this partition is not allowing me to convert. i am using minitool partition wizard to modifying partitions.

When I type reagentc it tells me is not recognized as an internal or external
Pleas help

Hi can you help me with my problem
I recently uninstalled my old hdd from the pc (doesn't contain windows in it)
And my pc doesn't want to show windows manager on my m.2 that has windows on it i can't boot into windows anymore with that ssd
I tried to install another m.2 with windows on it and it works just fine
I was using my pc normally until I removed that hard drive

cant i delete recovery partition and make one right after i convert it to gpt

How can I solve this problem
C:\Users\BOSS>mbr2gpt /convert /allowfullos EnablePrivilege: AdjustTokenPrivileges failed (Error:0x514)

ERROR: Failed to enable backup/restore privileges. Check that you are running in a process with elevated privileges.

My computer don't boot anymore bcs of the mbr2gpt.exe 😢

I GET THE FOLLOWING ERROR - ValidateLayout: Dynamic volumes/Storage spaces are not supported.

thank you

This video was a life saver. Finallly since Windows 11 came out, my computer is ready for it! Before… mbr2gpt wouldn't make the conversion of my system disk and it turns out because of an extra partition. With the help of the video i could delete it and convert my system disk to gpt.

cannot find room for the efi system partition what could this error be?

Thank you

You selected a terrible voice and unacceptable speed

I did the same steps, but now i get an error that says media check fail.. And cant get into windows. Please help

I only have 3 partitions

What if your new computer does not have legacy mode in the Bios and your old computer backup is MBR?

Thank you so much for This video..

I searched for many video to fix this problem, but this is the only solution I found so far, very helpful! thank you!

Please ans my question if I put this command after all the steps mbr2gpt /convert /allowfullows
It's showing invalid argument-/allowfullows
Please help me 😫😫

I only have 2 partitions in my disk and cannot get mbr2gpt to convert or even validate.

At this point I know my system is using BIOS legacy mode and has UEFI and secure boot available but do not want to start over from scratch with a fresh UEFI Windows install. This is such a pain.

Really thank u man!!!
