  1. Upgrading from Windows 7 to 10 - UEFI or Legacy?


    So im upgrading someones laptop from Windows 7 SP1 to Windows 10 and have created a backup image of the computer just in case with macrium. This is a pretty old dell E5250 laptop. As far as i know the 250gb SSD is on MBR and uses legacy BIOS. I plan on just doing the upgrade not a clean install. If i do it via boot menu can i choose either option or do i have to choose legacy? If i do it through just the media creation tool and click upgrade this PC what option would it use by default since i don't think it tells you?

    :)

  2. Trouble installing windows 7 on RAID in UEFI

    As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

    Trouble installing windows 7 on RAID in UEFI

    I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.

    Upgrading from Windows 7 to 10 - UEFI or Legacy?

    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
