    Missing Recovery partions - is that a problem?


    In preparation for converting my boot drive from MBR to GPT I ran Disk Management and noticed I have no Recovery partition. This has caused no problem or I would have noticed it before, but is it going to be problematic in the future? MBR2GPT /validate reported no problem so I assume the conversion will work but I would rather fix things that need fixing before doing the conversion.

    BTW, my test PC had two recovery partitions (which did cause MBR2GPT to choke) so this all averages out, I guess.

    It should not be a problem. Why do you want to convert to GPT?

    Actually, I have no need for GPT but I want to boot EUFI rather CSM mode. I would like to be able to try Secure Boot, and my recovery tool - Acronis True Image - has some recovery features that either require, or are easier to use, with UEFI boot. (And yes, I know that Macrium Reflect is much beloved on this forum, but I want a backup tool that supports both SMB and FTP access to NAS storage.)

    GPT is not required to boot in UEFI.

    I understand very little about either MBR vs GPT or traditional BIOS vs UEFI. On my test PC prior to running MBT2GPT, if I did not have CSM support enabled the boot process could not find a bootable drive, and after enabling CSM support I would boot into "Legacy" mode. After running MBR2GPT I would boot into EUFI mode. (I have not tried disabling CSM support, but I assume it will boot fine when I do.)

    Regardless of MBR or GPT, running MBR2GPT seemed to build whatever is needed to perform a native EUFI boot and was a trivial process (once I deleted an unneeded extra Recovery partition). There may be another way of achieving the same goal without converting to GPT but I see no reason not to use MBR2GPT.

    Well, this is going to be a bigger job than I imagined. MBR2GPT failed because it could not shrink the OS partition. Disk Management shows an available shrink size of 0. (I bet that's why I don't have a Recovery partition - no room for it.)

    Try using a free 3rd party partition manager e.g. Minitool partition wizard, Aomei....

    Disk Management can't do everything.

    I'll look into them. But even if I get the partition shrunk, I'm worried about why Disk Management could not do it. Will I be able to recover into the smaller partition or is there something Windows has put at the end of the partition that is unmovable without a reinstall of Windows?
