why can't I dual boot after I installed Ubuntu 12.04
I installed Ubuntu 12.04 and was able to dual boot with no issues. Then I mad the mistake of missing with the partition label. when I tried to restart my computer it said error unknown system file. I was able to use the Ubuntu live CD to download boot repair. Now I have my windows XP OS working fine, but i can't dual boot. I delete Ubuntu 12.04 and reinstalled but still can not dual boot. Is there someway to fix this. Yesterday was the first time in terminal, so if the solution is through that I will need step by step direction for dummies. Thank you in advance.
