  1. Cannot UEFI boot on another drive


    Hello,

    I am using a laptop with 2 drives. Lets call them Disk0 and Disk1.
    On both disk I have installed windows pro.
    I thought i could simply tell in the BIOS on which drive to boot but it did not work like that, so I decided to install AIOBoot and Clover on a Fat32 partition on Disk1. It helped me switch from one windows to another. Each time I was telling the AIOBoot to change the bootloader from Disk0 to 1 or 1 to 0 depending on what i needed.
    Recently I decided to encrypt disk0. It was stupid as I did not think about the clover bootloader - Clover did not see the disk0 anymore. Then I could not boot. I used a USB key to boot on the encrypted drive and decided to stop the encryption.
    Now I do not know what hapened but I am struggling to boot into the other disk1 and I get a bluescreen with an error of wdfilter.sys
    However I can still boot on the disk1. No idea why.
    Is there a way to have the disk1 booting. Is it a simple error because of wdfilter.sys?

    :)

  2. Install Windows 10 using UEFI bootable USB thumb drive

    You need to go into you system bios and select allow uefi usb drive. Then add the UEFI usb drive to the boot menu

    better way to partition aand create an bootable usb.

    For the UEFI system, we can use these steps to create the bootable USB:

    1.Locate a 4GB or larger USB flash drive

    2.Open Diskpart and run the following command cmd admin type diskpart

    • Type DiskPart in the command prompt.
    • Type "List Disk” (make note of the disk number of the target USB drive).
    • Type "Select Disk X”, where X is the target USB drive noted in step 4.
    • Type "Clean”.
    • Type "Create Partition Primary”.
    • Type "format FS=fat32 quick”.
    • Type "Active”.
    • Type "Assign".
    • Type "Exit".

    Copy your ISO files to the drive and reboot

    never use UEFI it better to repartition and remove UEFI go with legacy bois

    AsRock Z77 Pro3 - AHCI? UEFI?

    UEFI is a new standard of bios design, so that would probably be what the BIOS has listed as the first boot option, where ACHI is a mode that SATA controllers run, and that is probably listing drives by order of first to last by port order. Not sure why it would list that way (if my guess is right as to how/why it is listing the drives).

    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
