In looking into upgrading to windows 11, I learned that I would need to enable secure boot on my pc, which would require switching from legacy boot to UEFI boot. This apparently is not as easy as it would seem and every indication (setupact.log, system information) is telling me I'm using BIOS instead of UEFI. I'm trying to figure out if my motherboard is UEFI compatible, and if it is, how do I switch over? Thanks!

I"m having a hard time getting everything checked so I can install Windows 11. The core issue is this part
" To change these settings, you will need to switch the PC boot mode from one enabled as “Legacy” BIOS (also known as “CSM” Mode) to UEFI/BIOS (Unified Extensible Firmware Interface). In some cases, there are options to enable both UEFI and Legacy/CSM. If so, you will need to choose for UEFI to be the first or only option."
When I change it to UEFI only for Boot Device Control, then I do not get any boot options available.
The bios system still reads the hard drives, just says that no bootable devices are found.
I use a Samsung 980 NVMe for the OS, and also have one 850 EVO and 850 Pro Sata.
I have updated the BIOS to the latest as well (same issue remains w/ no bootable devices found), where it says nothing should have to be done for Windows 11.
Thanks for any assistance.
*edit, I found something related to MBR to GPT, seeing if this applies to my situation*
*edit 2: it is solved now, converted to GPT using the command through the cmd*
Hi,
Do the following: download PC Check Health, take a screenshot, and post a picture of your PC here:

Windows 11 requires that the device be UEFI- and Secure Boot–capable, have TPM 2.0, and meet the other minimum hardware requirements (CPU, RAM, storage, graphics, display, and Windows version) before Windows Update or the Installation Assistant will allow the upgrade.
From the described configuration:
- Firmware TPM 2.0 is enabled and visible in
tpm.msc. - Secure Boot is enabled in UEFI and reported as active in Windows.
In this situation, the remaining checks to focus on are:
- Confirm UEFI (no Legacy/CSM) and Secure Boot mode
- In UEFI firmware, ensure the system is not booting in Legacy/CSM mode. The firmware must be set to UEFI mode, with Secure Boot capability enabled. Some systems allow both Legacy and UEFI; in that case, UEFI must be the first or only option.
- If needed, use the Windows path to UEFI settings:
- Open Settings > System > Recovery.
- Under Advanced startup, select Restart now.
- On the blue screen, select Troubleshoot > Advanced options > UEFI Firmware Settings and then Restart.
- In the firmware menus, verify that Secure Boot is enabled and that the system is booting in UEFI mode, not Legacy/CSM.
- Verify all Windows 11 minimum requirements
- Storage: At least a 64 GB or larger storage device must be present.
- System firmware: UEFI and Secure Boot capable (already configured, but must be recognized as such by Windows).
- TPM: TPM 2.0 (already confirmed via
tpm.msc). - Graphics: DirectX 12–compatible with WDDM 2.0 driver.
- Display: 720p or higher, >9" diagonal, 8 bits per color channel.
- Windows version: The current OS must be Windows 10, version 2004 or later, to upgrade via Windows Update.
- Use firmware menus to confirm boot mode
- If there is still doubt about the boot mode, use the firmware boot menu to see how the OS drive is listed. For example, entries like UEFI: indicate UEFI mode. If only BIOS/Legacy entries appear, the system may still be in Legacy mode, which will block Windows 11.
If any of these checks fail (for example, the system is actually booting in Legacy/CSM mode or the current Windows 10 version is older than 2004), Windows Update and the Installation Assistant will continue to report that the device does not meet requirements even if TPM 2.0 and Secure Boot appear active.

Hi.
I have the following configuration of disk drivers:
Disk 0 (Basic MBR) - Sata 7200 RPM
- System Reserved 50 MB
- F: (NFTS)
Disk 1 (Basic MBR) - Sata 7200 RPM
- D: (NTFS)
Disk 2 (Basic GPT) - SSD 840 Evo
- E: (NTFS)
- ? (NTFS)
- ? (FAT32)
- Other
Disk 3 (Basic GPT) - SSD 980 Evo Plus
- G: (NFTS)
- Other
Disk 4 (Basic GPT) - SSD 980 Pro
- C: (NTFS) -----> My current OS (Windows 10).
So, I changed my UEFI / Bios settings, to use UEFI and use secure boot too, but I can't load my OS and I don't know why. Maybe it has something to do with the configuration of my disk drives. Can anyone help me here? Should I convert the Disk 0 to GPT too? Is that the problem?
Hello, I'm trying to prep my pc for windows 11.I have a an ASUS Tuf Gaming x570-PLUS (WI-FI) mother board.
I downloaded 'PC Health Check' tool from windows.
I updated my BIOS to v4021. However I'm still getting an error that my 'PC must support Secure Boot'
I double checked in the in BIOS and it looked enabled with the Windows UEFI mode turned on.I've restarted my pc multiple times and still nothing.
Some PC Info:
Motherboard: ASUS Tuf Gaming x570-PLUS (WI-FI) BIOS v4021
Storage: SAMSUNG E 1TB 860 EVO 2.5 SATA3 SSD
CPU: AMD RYZEN 7 3800X WRAITHP

Anything to report about this new beta bios I'm personally waiting for the final bios.
