I have a Toshiba Satellite laptop, originally with Windows 7 but then upgraded to Windows 8, so I don't have any install disks or anything.
I was doing some testing on a Linux distribution (Ubuntu 13.04 desktop, if it matters), and I had the partition taking up a good bit of my hard drive. As you probably know, Ubuntu installed its own grub bootloader and got rid of the Windows 8 one.
After I was done testing, I booted Windows and then deleted the Linux partition from within a partition manager. There were two problems: when I deleted the partition, it deleted the grub bootloader, so my machine wouldn't load for quite some time, and I also couldn't expand my Windows parititon so I had 200 GB of unallocated space I couldn't use.
Since I don't have any install disks or anything to fix the MBR, I finally gave in and reinstalled Linux on the other partition. Now I can boot fine and that problem is solved, but I can only use half my hard drive and I have another OS I don't want.
Is there anyway I can just delete the other partition and expand my Windows one to the rest of the hard drive, like the way it was set up before? So far nothing I've tried has worked. Thanks!
