    Changing from Legacy Bios to UEFI, settings in bios and Windows 10


    I used the Windows converting program MBR2GPT.exe to convert my SSD to GPT and it reported it had done it. I then rebooted and entered the bios and changed one setting from Legacy ROM to EFI Compatible ROM and another setting called 'UEFI Boot' from Disabled to Enabled and saved. When I booted nothing happened, it was like it saw nothing was connected to the MB and I had to clear the bios and put my cloned drive I did not change to GPT back in. Not sure what I need to do the get it to work? I have other drives in the system too: another SSD and two HDDs in RAID. Do I need to change them also to GPT? They are just for storage.

    Thanks for the help in advance.

    :)

    Problem Regarding Bios Change from UEFI to Legacy

    I have hp pavilion p045tx with windows 10 pro. I recently install Ubuntu with windows 10 so for that I convert my bios setting from UEFI to Legacy mode for install third party software like wireless Driver and all in Ubuntu.
    But after every restart the bios setting change to default and that is to UEFI mode and that will cause an problem of no OS detect. Every time I have to go to bios setting and enable the legacy mode to start my OS. Can anyone suggest me what to do in this
    case.

    Return to Legacy from UEFI - BIOS

    Hi There

    A while ago I was helped here to change from Legacy to UEFI. However, since then it seems, the Laptop (Latutide E6420) is running a bit slowly which was otherwise very quick until then. Now, it takes nearly a minute or so to boot up or shut down or even
    to close a file. Just a couple of days ago, I updated the latest BIOS for this machine recommended by Dell.

    I tried to go back to Legacy but the system was asking me to reset to UEFI or face boot problems. One advise said that I could disable 'Secure Boot' in Boot Manager and reset to Legacy. However, the Boot Manager is listed under UEFI Boot process and it only
    starts Windows. Is there any way as easy as I changed it? This is absolutely under the hope that all will be as normal as it was in the beginning. Please give your thoughts and advice. Thanks.

    Changing from Legacy Bios to UEFI, settings in bios and Windows 10

    Legacy to UEFI

    I'm debating moving to UEFI form my now legacy BIOS (Award Software Int.) the mother board is a GA-Z68XP-UD3 rev1.0 on the the following link it shows a UEFI BIOS U1J )UEFI BIOS)

    GA-Z68XP-UD3 (rev. 1.0) | Motherboard - GIGABYTE Global

    Currently I'm running the legacy F10 BIOS. Does installing the UEFI BIOS automatically take care of everything to get to the UEFI BIOS? Installing the UEFI BIOS following the instructions using the Q-flash method GIGABYTE How to Reflash Motherboard BIOS

    What's steps do I take and in what order?

    Much appreciated
