Hi I got a new HDD (samsung 500gb 7200 16mb) and i cant install windows. The discs i have arent dedicated MS XP discs but are acer recovery discs as my pc once was an acer SA80. I have used the discs once before and they worked fine but that was with an seagate 160 HDD im wondering if thats the problem or should it take longer to install as new HDD is bigger. I let the second disc run for approx 15 minutes but it didnt appear as anything was happening??? Please help!
