Getting rid of damaged Windows 7 dual boot

Postby Andy2718 » Fri Oct 13, 2017 5:54 pm

I'm a newbie and this may be complex so please go slowly!

I've ended up with a dual boot mess. I've put Mint on my old Win 7 machine but (a) Windows 7 won't boot at all and (b) Mint can't see the old Win 7 data because Windows has the dreaded Fast Restart switched on so Linux thinks Windows is always active and (c) I can't switch Fast Restart because of (a). What I'd like to do is to kill Win 7 dead with a stake though its heart; and if possible, I'd prefer to preserve the Windows data. So I'd prefer not to simply format the disk with Mint and then re-install Mint. This must involve deleting some kind of master boot record or something, please can anyone tell me in simple terms how to do that? I'm not sure what information to provide but in case the inxi output is useful, that is below my signature.

Many thanks

Hi, Andy. We're going to need to know what your partition layout looks like.

Please start a terminal and post the output of this command:

Code: Select all

sudo lsblk -f

Enclose the results in code markers, which you can select from the mini toolbar above the textbox where you type your reply.
If your problem is fixed, please mark your thread as [SOLVED] by editing the title of the first message in the thread.

you should learn if your computer is UEFI or Legacy and if uefi disable secure boot and enable legacy support in your bios settings first. if you have these already than are you able to boot to mint? if so
sudo os-prober
sudo grub-install /dev/sda <<< if a is your boot drive
sudo update-grub
I love Windows, they give my walls personality.

Pouring salt and garlic on the Windows install disks might stop reinfection. :D

For people looking at preventing this situation, splitting the Windows C: drive into C: for Windows and D: for your home directory is a good idea. You can then backup and recover your Windows data easily compared to a single drive C:.

OK, I now know the partition structure (posted above), what next please?

Re Uefi / Bios, how would I check that?

Many thanks

so - - do you still want to dual_boot ?

- or just keep win-7 & ditch Linux
- or just keep Linux & ditch win-7?

do you have the Installation disk / ISO for each system ?

if the machine came with win-7, then it won't have either UEFI or GPT issues

more importantly - - is there anything of value - on either system,
- that is not already backed-up ?
