I was using 2 OSs, Windows 7—installed on C:—and Ubuntu—on a 60 GB partition next to G:.
Now, I changed the processor and motherboard and reinstalled Windows. Ubuntu was left untouched. When I start my PC, I’m missing the option to choose between Windows and Ubuntu.
I understand that on installing a new processor, I need to reinstall the OS.
I’m not able to get access to that 60 GB partition next to my G: drive so that I can format it! I went to Disk Management in Computer Management and I found the 60 GB partition. When I hover the cursor over it, it just shows “Healthy (primary partition)”. On right clicking, everything but the “Delete” option is grayed out—including the “Format” option! I want to reclaim those 60 GB.
