My computer has windows 7 and Ubuntu 12.04 on a dual boot with grub, and I want to upgrade to 13.04 with a fresh install and grow the partition.

the method I want to follow is this one:

  • Go to the windows disk management and format swap and Ubuntu partition
  • grow partition with disk management (from 30 GB to 120 GB)
  • boot on bootable usb stick install Ubuntu 13.04 along side windows 7 like in this post

My questions are:

  • will this mess with grub?(more unusable boot options or something)
  • is it safer to use windows disk manager application for formatting the partitions instead of gparted?
  • imagine I can't install Ubuntu after I formatted the partitions, will this make my machine unbootable? how do I solve this?

Probably not, GRUB is generally pretty good at working after an upgrade or similar

is it safer to use windows disk mannager application for formating the partitions instead of gpart?

Most definitely not. Windows Disk Management cannot create ext4 or swap partitions as you would need to run Ubuntu. You would be better off using GParted from the LiveCD when you install Ubuntu or even the partitioner in the Ubuntu installer

imagine I can't install ubuntu after I formatted the partitions, will this make my machine unbootable? how do I solve this?

You can use Boot Repair from here
