Why can't I boot Ubuntu on my laptop from my USB Drive?
I recently chose to use my Micro Center 32 GB storage, so I switched my other flash drive and installed Ubuntu on the main USB. I arranged the partitions properly—fat32 first, then ext4 for the Ubuntu area, and a swap third. I also turned off secure boot in the BIOS and set it to boot from any USB first. Despite these steps, it still doesn<|pad|> to work. I attempted to reset partitions with gparted and reinstalled GRUB using boot-repair, but nothing happened. Someone mentioned switching to legacy mode instead of UEFI in the BIOS. I tried that, but it won’t boot and asks for a media player instead. It seems the legacy mode might be flagging my USB as bootable while UEFI doesn’t. If this is the case, how can I resolve the legacy mode issue? If not, what should I do next?
The alternative version I used to install Ubuntu was 16 GB, which should also be compatible. It's PNY.
I've encountered issues with multiple drives, but Lexar typically resolves them during startup.
