PopOS not UEFI64 booting

Open steve6375 opened this issue 3 years ago • 3 comments

pop-os_20.04_amd64_intel_13.iso tested using VBox v5. Boot from Easy2Boot to agFM - hangs (?) during boot (last stage just before screen clears and desktop shown). If I UEFI64-boot to agFM then load Ventoy - Ventoy also has same problem. Freshly made Ventoy USB stick also hangs on UEFI64 boot in same way. MBR booting (Ventoy, grub4dos and agFM) is OK. If I first MBR-boot to Clover UEFI64 - then load agFM UEFI - then it boots from ISO OK. image

I can extract ISO files to a FAT32 USB drive. UEFI64 boot in VBox 5 - same problem ! Maybe bad ISO build??? I notice ISO has symbolic links when using 7zip to extract files - maybe it only works if you dd the ISO as an image to a USB drive.

I tried it on a real system and it works! It must look for a USB drive.

but why Legacy-BIOS booting is OK in vbox?

If I first MBR-boot to Clover UEFI64 - then load agFM UEFI - then it boots from ISO OK.

maybe Clover UEFI64 on Legacy-BIOS has CSM? https://github.com/pop-os/pop/issues/595
