Hi,
This is also a small problem which happens quite often. Please tell if
a) You already have another Operating system installed in the same machine (Win, Mac, ...)
Or if not
b) When the boot screen seems to appear (the circle icon), please wait about 10 sec and then press CTRL+ALT+F2
You should get access to console. Then please insert a USB stick and mount it from that console. But before that,
Command:
dmesg | tail -10 | grep sdb | grep Attached
If that command does not output anything, then this becomes unfortunately
a bit harder to explain and I suggest that you leave the system as it is, or send me
a pm so that we can make sense about it.
BUT, if the command made some output, then
make sure that the USB is formatted first - or just command mkfs.vfat /dev/sdb1
(and make sure you don't have anything important in that stick), since it will be formatted.
Then mount the USB to /mnt. Command:
mount /dev/sdb1 /mnt
Then:
dmesg > /mnt/dmesg.log
Then shutdown Linux Lite:
sync; cd / ; umount /dev/sdb1; systemctl poweroff; exit
Then insert the USB stick to a working computer and send the dmesg.log -file here as an attachment
Let's see what it is this time
