Will upgrading Windows mess up my dual boot?

[Njabulod]

I want to upgrade Windows 7 to 8.1, my only worry is that I don't know if this might affect the dual boot I have on my computer. I certainly don't want to see burg disappear after upgrading. Is there a way of doing this without compromising my grub/burg?

Go read MSCONFIG boot tab and copy text. You tube how to set dual boot on win 8.1 and re insert second boot option. if it is on one HDD don't format.

Backup your MBR with dd, upgrade and if you have issues restore the MBR.

The easiest way is to do the upgrade, which will destroy your grub boot-loader. Thereafter, repair the grub boot-loader by following the following procedure:

Boot up from a live Linux CD.
First you need to find out what your drives/partitions are called. You can do this by opening a terminal and typing:

sudo fdisk -l

From the output you need to find the device name of your target linux partition, something like “/dev/sda5″.
So, still in the terminal, type:

sudo mkdir /media/sda5
sudo mount /dev/sda5 /media/sda5

And then, to re-install the grub:

sudo grub-install --root-directory=/media/sda5 /dev/sda

Of course you need to replace "/dev/sda5" and "/dev/sda" with what you found in the fdisk output.

The above works for mint as well?

Should do.

Might be easier to boot from a Super Grub 2 CD (http://www.supergrubdisk.org/super-grub2-disk/) into your Mint installation and run grub-install device (use df to find your device, probably /dev/sda).

Thanks everyone. I've just upgraded to 8.1 and my boot loader (Burg) wasn't affected at all, I'm thinking maybe it's because I was using Windows 7 SP1 which is 64 bit, on a 32 bit machine I doubt it would turn out the same.
