Installing Debian on a Win7 laptop. Install goes fine, but reboot takes me too:
Thoughts.

Do you have a bootable partition somewhere? What does
fdisk -l
say?

This was a complete wipe of Win7 in replace with Deb stable, so in theory there should be a grub config on there.

Reboot in Rescue Mode off install USB shows me that the LVM volumes are there. Try to grub install to EFI volume fails, as does doing a grub update.

fdisk
output flys by (no

in
busybox
), but seems OK as far as I can see.

I think the EFI partition is the problem. Here is the end of the
fdisk
output:

From the initial top screenshot it looks like the boot order is set to something else than the bootable partition you want, and so the BIOS complains it cannot find a bootable partition or image. What is the boot order?

Some option in the BIOS that's blocking the grub install or modifying the EFI?

In pic 1, netboot was on, so on finding no boot medium it tried that. Now off I just get no boot medium. I think grub info needs to be on sda1
and
the EFI partition.

Your 336M empty partition is set as bootable, you probably want the EFI partition as bootable instead. Afaicr you have to enable expert mode (x) in fdisk and use the 'A' option to toggle the bootable flag on the correct partition.

There is a bit about EFI in

and maybe you will something useful. Best of luck, @

So I got on with the other install I had to do, but I'm back at this one now.

Just run
fdisk /dev/sdb
, then type
x
and hit enter. You're now in expert mode. Type
m
and hit enter to see available commands.
A
toggles the boot flag for legacy BIOS boot, if I remember correctly it will ask you for which partition you want to toggle. When happy, press
r
and hit enter to go back to normal mode, then
w
and enter to write the partition table to disk and exit.

I see...it was difficult to see what was greyed out from the photo.
Can you post a screenshot of the BIOS section "boot"?

I messed around with
fdisk
expert mode trying to get the boot recognized, but failed. Redid the install and it booted properly. Go figure.
