Proxmox UEFI Not Booting |Solution

UEFI boot support has been added to Proxmox VE version 7, enabling UEFI mode booting for VMs. On Proxmox VE, there are a few possible causes for UEFI boot problems, though. Here are some potential fixes we could try:

1. Initially, verify that UEFI booting is supported by the hardware on which Proxmox VE is installed. A system with UEFI firmware, as opposed to conventional BIOS, is necessary for UEFI.

2. Make sure that “OVMF (UEFI)” is selected for the “BIOS” setting when building or modifying a virtual machine, rather than “SeaBIOS (Legacy)”. This allows the virtual machine to boot from UEFI.

3. Verify that the UEFI entry is properly set by looking at the boot order in the VM’s setup. It ought to take precedence over the other boot options.

4. Make sure the OS we are installing is UEFI-compatible if we are doing so from an ISO or image file. For UEFI boot, certain operating systems have unique ISOs or installation media.

5. Try temporarily disabling Secure Boot if the hardware or virtualization platform supports it to see if that fixes the boot problem. There are situations when Secure Boot makes some operating systems incompatible.

6. Make sure the firmware on the server—BIOS or UEFI—is current. Outdated firmware can cause problems when trying to boot from UEFI.

7. Furthermore, confirm that Proxmox VE is up to date on the system, as updates frequently bring bug fixes and enhancements.

8. Examine the logs and error messages supplied by Proxmox VE for further details if we run into any particular error messages or problems with the UEFI boot process. These can assist in determining the precise source of the issue.
