Ok, I've got a problem I could use help with. I've spent 4 hours googling for a solution and found absolutely nothing. And I'm not sure if this was asked before so sorry if I'm posting something that already exists. Anyway, here it goes...
I've got a XP/Ubuntu 12.10 dual-boot, last week I got a Win7 disc so I decided to replace my old XP with Win7 x64. I use Ubuntu for more-or-less everything except 3D modeling for which I need Windows.
And here's the problem, XP is on an active partition and as far as I understand, if I remove XP and install Win7 I won't be able to boot into Ubuntu anymore because installing Win7 will change the Master Boot Record.
I want to keep Ubuntu intact and only replace XP with Win7, I know it should be possible but I don't know how to achieve that. All I've found so far is that I should make a backup of the MBR, restore it after I install Win7, boot into Ubuntu and set GRUB to boot Windows but I can't find any details or instructions about how to do that anywhere.
So I'd really appreciate some help with this.
