Thanks yancek. Can't connect to wifi when booted from the usb stick, back on windows. Yes, I used esc key then f9, it showed an Ubuntu boot manager, I chose that and exited. When I did sudo mkdir /mnt/efi I think it did make the directory, but I messed up the second command so badly that I exited and started again and got what's in the screenshot.

I can't see any mention of Ubuntu or Mint in boot options. Secure boot and fast boot are disabled.

It appears to me that the install was not written to the disk. If that is correct how can it be fixed?

OOps, the screenshot was saved in Linux, and I can't get here from there so I'll type them in from a photo on my phone.
sudo mkdir mnt/efi
mkdir: cannot create directory 'mnt/efi': no such file or directory
sudo mount /dev/sda1 mount/efi
mount: mnt/efi mount point does not exist.
/mnt/efi
bash: /mnt/efi: Is a directory

I did make some more screenshots but I didn't take pictures of them I'd have to go back to Linux to get them, that would take a while because I'm a very poor typist.

yancek, Sorry I didn't find your post when I checked earlier before falling asleep for a long nap. Did I do an efi install? I don't know.

colorpurple21859, Thanks for that, I'd forgotten it. How would I check the Linux partitions to see what is there?

Sorry to be so dense about this, all but one of my previous installs have just used the whole disk. The one exception ended up wiping Windows, so I'm a bit skittish about it.

boot into the live mint,
open a terminal
will show an efi directory if your in efi mode.
create a /mnt/sda6 directory and mount your mint partition
to list what is on your mint partition:
to display what is in /etc/fstab(file that tells what gets mounted at boot time)

On the old computer now, colorpurple21859, I ran thru that list of commands on the new computer, most returned no such file or directory. I have screenshots. I'm going to take time out and try to setup wifi when booted to usb, having a bit of difficulty with that, hope I can send screenshots if I get wifi going.

Back on windows, old asus froze up when I had this almost done, it's dieing. Typing from phone pictures now, no luck with wifi. Commands I typed are perseded with mint@mint:~$

ls /sys/firmware
acpi dmi efi memmap
sudo mkdir /mnt/sda6 /mnt/sda6
mount: /mnt/sda6: special device /dev/sda6 does not exist
ls mnt/usb
ls: cannot access 'mnt/usb': No such file or directory
cat /mnt/sda6/etc/fstab
cat: /nmt/sda6/etc/fstab: No such file or directory

I redid a couple that I thought I had mistyped, I think there is at lest one more, I'll go back and rerun it later.

sudo mkdir /mnt/sda6
mkdir: cannot create directory '/mnt/dev/sda6': File exists
sudo mount /dev/sda6 /mnt/sda6
mount: /mnt/sda6: special device /dev/sda6 does not exist

I'll boot back onto the usb stick, check the list of commands again, and try to correct my mistakes

I hope I got it all right, I can easily overlook things. I'm getting tired and it's bedtime. I'll check back tomorrow. Dr. appointment in AM so will be away a while.
Thanks to every one of you for your help and patience.

Not knowing what the two linux partition are, change each sda6 in post #48 to either sda4 or sda5 depending on which partition you think is your root partition and see if that works.

Ok, slow process but I'll get started. Root is sda4

The commands suggested in post 44 and 48 were entered incorrectly which is why you got the errors you did. You missed the beginning forward slash ( / ) on several commands and entered an incorrect command in others. Take a look at the posts again try them and type them exactly as shown.

here take a look at my thread when I was having an issue after installing MINT LINUX UEFI system and how I fixed it, toot sweet.

Thanks yancek. I saw that I had missed the beginning /, I thought I had went back and corrected it, but I can make the same mistake twice and not see it, I'll get on it, changing any reference to sda6 to sda4

I brushed the keypad and got lost, will have to redo this and read the link posted by BW-userx after i get back from appointment. I think it was the same as the return from the previous cat command. Got to go now.

I meant the touchpad, trying again.
