Hey everyone! I've got an older PC that suddenly stopped booting into Windows and just goes straight to the BIOS. I didn't really pay much attention to it since I wasn't using it. At one point, I managed to install Linux on it, but it was super laggy because it was running off a USB. After a while, I decided to wipe everything clean and try installing Windows again, but it wouldn't work. I suspect it wasn't recognizing my USB or the SSD.
To fix this, I got a new SSD and tried using a bootable USB to install Linux, but I keep running into different problems. I even tried various USB sticks, but nothing seems to work. I've seen various error messages, like:
- Failed to open LEF\bootimmx64.efi - Not Found
- Failed to load image: Not Found
- Failed to start MokManager: Not Found
I've done some research online, but the solutions I find either don't work or are way too technical for me. One solution actually worked until I had issues with partitions during the Linux installation. I've tried disabling secure boot in BIOS, but sometimes the PC just doesn't recognize any bootable device. I've also tried flashing the USB through different programs.
Honestly, I just want to figure out what's going wrong instead of paying someone to fix it. I'm still learning, but I've hit a wall here. Any help would be greatly appreciated! Thanks!

I’d recommend testing the USB on another working system first. If it works, the issue might be with your PC. If it doesn’t, then the USB stick could be faulty.
EDIT: Something's definitely off with your SSD or the PC in general.
Bootloaders can get corrupted, which could be causing the issues you're seeing. Try booting into a Linux live session first. You may want to format your drives and start fresh with Windows if that’s your goal—don't forget to delete and format the old Linux installation if you're switching back to Windows. Also, tools like Rufus can help adjust settings related to secure boot and TPM if those are causing hiccups. If you're interested in dual booting, I suggest setting up separate drives for Windows and Linux. Just keep in mind to set up your BIOS to allow for the bootloader correctly.
