Mint 19.1 install as dual boot on Win10 Toshiba Satellite Pro/ Win10 cant update/ changed boot order to Win10 first lost boot menu lost Mint

I looked up how to change boot order on dual boot system. Can't recall actual youtube video. Now Win10 boots normally with no selection menu but still when updating it mostly reports it cannot complete and has to undo everything. I can live boot from Mint USB and backed up all my Linux data files.

I tried to reinstall Mint from the USB and it stalled with a partition corrupt error. I looked at the partitions and do not know enough to decipher what to reformat to clear out Mint and start from scratch and particularly scared of breaking my Win10 access. It would be very helpful if I could restore the boot option menu and get back both.

Thank you for your assistance.

Boot any Linux live media from USB and collect output from parted -l or fdisk -l, and from efibootmgr -v, then paste their output here between code tags.

mint@mint:~$ parted -l

Booted to any live Linux media in UEFI mode, the following should get your Mint Grub back (without disturbing Windows bootability):

Code:

# efibootmgr -o 6,5,4,3,2002,2006,2004,2005,2,0,1,3001

Because your attempt to reinstall might have damaged the existing installation, simply having your Grub menu back might not be sufficient to boot Mint again, but Windows should still be in your Grub menu.

Apparently using what you booted you needed elevated permission to run parted and fdisk . Try again prepending sudo to each, or login as root first if possible.

Ok thanks but considering what you say i'll first run the sudo commands..

Nothing I see in post #5 suggests the efibootmgr command in comment #4 shouldn't work.

Thanks here is the result..

Code:

mint@mint:~$ sudo efibootmgr -o 6,5,4,3,2002,2006,2004,2005,2,0,1,3001

Thanks I think it is as you suggested.. Boot menu comes up with Ubuntu at top goes to this screen

Perform MOK management

Continue boot
Change Secure Boot state
Enroll key from disk
Enroll hash from disk

Pressing [continue] goes to [Toshiba >>>] hardware screen and stalls there. I had to do a hard power off

Selecting the third option
Win10 boots ok

I have not tried any of the other options..
If I cannot boot Mint can I reinstall it or remove it
Thanks

There should be instructions from an appropriate web search to repair Mint secure boot bootability. That's not something I've ever needed to do here.
