Mint partition flagged as "unallocated"

Postby kenta on Sat Jan 05, 2013 12:52 pm

Hello everyone!
Sorry for my english (i'm not a native speaker) and sorry if i'm posting something that's already been discussed.

I had a Windows partition not working, and a Mint partition working on my computer, when i decided to try repair the first one. I used the Windows CD and it repaired that partition (i can see it from GParted), but there comes another issue. My Mint partition is now Unallocated for Gparted. I tried the liveCD and the liveUSB (both Ubuntu and Mint), but it seems that my partition is no longer there. I would simply install the system another time, but it seems too strange for me to be true. The fact is, the partition was a primary partition with two secondary partitions (Mint and Swap), and while the swap is still there, the mint one is disappeared. I can't see why this is possible (and why windows could format another partition without touching it).

If it matters, the systems are Windows 7, Mint 14, and now i can't boot from either one because grub is not there,
anyone can help me?

Linux Mint is funded by ads and donations.

TestDisk may correct the partition table. You can run TestDisk via linux liveCD/USB, and you can install TestDisk via package management.

I agree with oobetimer; your best bet is to use TestDisk or some equivalent utility.

To address some of your confusion, though, Microsoft's partitioning tools are known to have bugs that can cause them to delete partitions. This is one of the reasons that many Linux users strongly recommend against using Microsoft's partitioning tools except when absolutely necessary. That said, if Windows wasn't booting, you had little choice but to use those tools. You were in one of those "absolutely necessary" situations and Microsoft's bugs bit you.

Just guessing...

Perhaps Win repair has changed your physical partitions into its own dynamic volume..

May be you can boot from your ubuntu or mint Live CD/DVD, then on terminal type

sudo parted -l
sudo fdisk -l
and see what terminal can tell you.
