I have only pictures. And I can’t write the Question well.

I was starting my laptop (I have

Windows 10 Pro
and
CentOS8
).

systemctl status initrd-switch-root.service

The last image

Failed to Start Switch Root
. And

Failed to switch root: Specified switch root path '/sysroot' does not seem to be an OS tree. os-release file is missing.

Doing a

ls -al /sysroot
the directory is empty.

With

dmesg
i got:

enter image description here

any idea why this failure occurs?

And obviously, how I can solve it?

In the image, the only entry working is Rescue The CentOS entry that is above the Windows entry

CentOS Linux (0-rescue-***)
enter image description here

Please help.

EDIT 1 Using described on https://unix.stackexchange.com/a/212710/117555

  1. Check dev ->
    ls -al /dev/s*
  2. Insert the USB stick
  3. Check Again ->
    ls -al /dev/s*
  4. Create Mounting Directory ->
    mkdir -p /mnt/logError_SwitchRoot
  5. Mount the stick ->
    mount /dev/sd[letter][number] /mnt/logError_SwitchRoot
  6. Copy the File ->
    cp /run/initramfs/rdsosreport.txt /mnt/logError_SwitchRoot
  7. Umount the stick ->
    umount /mnt/logError_SwitchRoot

I have now on
