[SOLVED] USB not booting

wpeckham · 04-08-2023, 12:49 PM

You might want to check your hardware (bios) settings and look at the boot order. If you put USB before HARD DISK in that list it should use the USB to boot form if it finds a boot ready drive there.

Hi colourpurple, Here's the output from the code you gave me to execute. Thanks for you continued perseverance with me.

Is secure boot and fast boot disabled in the bios/firmware?

walesjoe · 04-10-2023, 08:04 AM

Hi colourpurple, I'll check whether secure boot is disabled. Meanwhile the following screen dumps illustrate what the contents are of the USB filesystem.

Hi colorpurple, I've checked the my Dell La[top system startup and confirmed secure boot is Disabled. Thanks.

based the "ls -R /media" output of "no such file or directory" the leap grub bootloader wasn't installed correctly.
try this at the grub menu to see if you can pull up leap grub menu, press c for grub> prompt

Code:

grub>configfile (hd1,2)/boot/grub2/grub.cfg

Hi colorpurple21859, I found a few commands from previous problems I had booting various Linux distros off USBs. Do these screenshots help identify my problem, or are you sure that my problem is definitely that the Leap grub bootloader wasn't installed correctly?

According to the screen shots in posts 17 and 18 after mounting /dev/sdb1 to /media there is no EFI directory on /dev/sdb1. Did you do the grub command in post 22?
On second thought add sudo to the ls command in post 15 after mounting sdb1 to /media, It may be a permissions issue.

walesjoe · 04-12-2023, 05:08 AM

I added sudo to the ls command, output from that is this attached screen shot. I will now try the grub command in post 22 and report back.

I used the configfile etc command at the grub> prompt and the screen cleared followed by the grub> prompt again. I entered Reboot, and the laptop booted up to the menu I get where I can choose Zorin, Mint or MX. I shutdown the laptop & booted again this time using the F12 key to get the boot options menu and there was no USB to choose to boot from.

try this at the grub menu to boot leap, press c for grub> prompt

Code:

grub> set root=(hd1,2)
grub> linux /boot/vmlinuz root=/dev/sdb2
grub> initrd /boot/initrd
grub> boot

walesjoe · 04-13-2023, 09:12 AM

I ran code you suggested & got this:
grub> set root=(hd1,2)
grub> linux /boot/vmlinuz root=/dev/sdb2
error: disk 'hd1,2'not found

at the grub prompt ls to list the drives that grub prompt grub> ls will list the drives/partitions that grub can access

walesjoe · 04-13-2023, 01:10 PM

I used the ls command at the grub>prompt & got:
(proc) (memdisk) (hd0) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (cd0)
