  1. Is there a way to access my data MBR HDDs and SSDs on a UEFI system?


    Hello,I have a 2TB HDD and a 480GB SSD which I used in my old setup MBR mode to store work photographs and games. I bought a SSD and installed Windows 10, now in UEFI mode, to be able to upgrade to Windows 11; it so happens that I can't upgrade anyway because my PC doesn't support TPM 2.0 and to my disappointment, found out those drives can't be accessed at all.The MBR2GPT command ruined the old Windows SSD and I don't fancy risking years of photography work and face days reinstalling games, so, is there any way to use those drives without changing them to GPT? Or should I just forget about

    :)

    Can I restore an image of UEFI system to a MBR partition?

    Is this feasible?

    I have Windows 10 on UEFI/GPT partition. I have an image created by Windows own backup tool.

    I got a small SSD which people say it's better to kept in MBR.

    Is it possible to somehow restore the UEFI system image to MBR SSD?

    Thanks

    Ugrading my 1TB MBR HDD to a 4TB GPT SSD

    You should do steps as follows

    1) clone 1TB hdd to SSD

    2) run mbr2gpt utility to convert ssd to uefi

    Convert Windows 10 from Legacy BIOS to UEFI without Data Loss

    3) extend 1tb partition on SSD to 4TB using tool like Easeus Partition Master (free version is ok).

    Step 2 is the critical step.

    Is there a way to access my data MBR HDDs and SSDs on a UEFI system?

    Transferring from BIOS/MBR system to UEFI/GPT

    This may be clear as mud, but I'm going to give it a shot.

    The SSD on my Dell 3847 computer failed, so I connected it as a secondary drive to another, older Dell (660) and was able to copy a lot of files off of it. That older computer has an HDD; I used it while waiting for Sandisk to send a replacement SSD.

    I first cloned the HDD in the 660 to my new SSD, but when I put it back in the newer computer, it couldn't be read; it said there was no boot file (if I remember correctly). I then created a system image of the older drive and tried to install it in the newer
    one with my new SSD, but that failed because the older one has BIOS with an MBR formatted HDD, and the newer one didn't like that; it has UEFI and wants to format to GPT. I then set about trying to convert the older one to GPT so a system image could be read
    on the new SSD, but found that, if I could do that at all, it would required wiping that drive, which is precisely what I didn't want to do. And I found that apparently the motherboard of the older computer can't work with UEFI anyway. The two Dell computers
    aren't all that different in their specs, so I never expected there to be a difficulty.

    I read in a few places that EFI is backward compatible with BIOS, but I got an error message saying that was the problem (when I tried to install the system image). Other online sources said they are incompatible in either direction. Since I can't get my
    old 660 to use UEFI, I'm stuck. It seems pretty clear to me that there is no way to clone (or create a system image of) the older HDD and have it work in the newer one. I went ahead and started from scratch with the newer one, using a Windows recovery drive,
    but I hate to have to set up all my programs. Am I right? Is there no other way?
