You need qubes os installation, boot from usb and select qubes rescue mode.
Type 1 and enter your Encrypted Password.
Ignore if there’s a pop up about you don’t have any linux partition.
type fdisk -l and find your /boot and /efi partition in my case it’s /dev/sdb1 and /dev/sdb2 then mount under /mnt
example : mount /dev/sdb2 /mnt mount /dev/sdb1 /mnt/efi
follow this step :
Boot device not recognized after installing
Some firmware will not recognize the default Qubes EFI configuration. As such, it will have to be manually edited to be bootable. This will need to be done after every kernel and Xen update to ensure you use the most recently installed versions.
Copy the /mnt/efi/EFI/qubes/ directory to /mnt/efi/EFI/BOOT/ (the contents of /mnt/efi/EFI/BOOT should be identical to /mnt/efi/EFI/qubes besides what is described in steps 2 and 3):
cp -r /mnt/efi/EFI/qubes/. /mnt/efi/EFI/BOOT
Rename /mnt/efi/EFI/BOOT/xen.cfg to /mnt/efi/EFI/BOOT/BOOTX64.cfg :
Copy /mnt/efi/EFI/qubes/xen-*.efi to /mnt/efi/EFI/qubes/xen.efi and /mnt/efi/EFI/BOOT/BOOTX64.efi . For example, with Xen 4.8.3 (you may need to confirm file overwrite):
finally umount your /boot and /efi partition and shutdown ( I prefer shutdown than restart, sometimes restarting took really long time, i don’t know why ) umount /dev/sdb1 umount /dev/sdb2 shutdown now
Hey guys,
I just spend 2k to buy a dell laptop and a SSD removable to start working with cubes, but I faced the same problem.
I installed qubes successfully and played around with it but after restarting my system, it didn’t show up on the UEFI boot option, I can see my SSD, but it’s not recognized as a bootable device.
I have reinstalled it 3 times now to make sure I’ve done it right, and I have verified the signature and authenticity of it
I tried the suggested routes on here but when I mount the sdb2, it replies with, it is either already mounted or it’s busy
when I try to mount the sdb1, it replies with the directory doesn’t exist
and it’s right because in the mnt directory the is just a directory called install and there is no efi directory inside it
ill be grateful if you can shed some light on this matter for me please
I can’t wait to start using qubes and I can’t
simply add uefi entry menu by booting into your qubes os installation medium, rescue qubes os, wait and type 3 to skip shell, lsblk to examine your external ssd, if it’s /dev/sdc then run
A new UEFI option was created and after choosing it, it went through OS recovery and repair, it was trying to repair my windows and said no issue found obviously
this is so strange, why is this happening?
Do you mind video calling me or something, please? So I can fix this issue
I am prepared to pay for your time you spend in helping me
thanks a lot
boot like before, and make sure your external ssd is /dev/sda (it could change, run lsblk first, if it’s still /dev/sda then no need to change command below, if it was /dev/sdb or /dev/sdc, change the /dev/sda below to /dev/sdb or /dev/sdc).
I needed to create an account just to congratulate this one… Very nice. I was months trying to install qubes, this was my last attempt… Now I am logged in.
