I tried making and running live Ubuntu zip drive and succeeded but somehow i messed up my previous MBR, HDD drivers, file system or maybe something else while trying to make a dual boot system. Now i am able to see my HDD from Ubuntu zip drive but windows 7(ultimate 64 bit) which was already installed and running prior to all this started to crash on every boot, also when i tried to repair it, some error came up, then again i tried to boot it from windows 7 bootable disc, its not detecting my HDD, althought i can see my partitions still there with diskpart command from command prompt through that disc.
I have a 500GB SATA HDD Seagate Previously it was partitioned as: 700KB 100MB C 63GB D 100GB E 100GB F 197GB
Now from running command prompt with a bootable win 7 disc and executing DISKPART command with select disk 0 and list partition commands i am getting
partition 1 700KB partition 2 100MB partition 3 63GB partition 4 437GB(Not exact)
I have some very important data scattered in partitions other than c: which is fully dedicated to windows.
So please help/guide me to bring my previous windows 7 back or reinstall it without effecting my data.
Or if it is not possible please tell how i can erase that 63GB partition and re-install windows 7 from scratch using command prompt since in GUI mode my HDD is undetectable.
