So... before someone gets mad at me for possibly repeating a thread... I ran the search on the forum for my scenario and couldn't find anyone who has experienced what I've experienced. That being said... here's my problem. I have a Macbook and I had Windows XP on my Boot Camp partition, but I wanted to upgrade to Windows Vista because my friend recently found their Vista install disc. I backed up all of my information from my Windows partition on my external hard drive, booted the Apple side, and ran Boot Camp Assistant. It made the separate partition, but then when it asked me to install Windows it said insert the Windows install disc, so I did... but instead of my Macbook restarting and installing Windows... it restarts... then you hear the CD drive/optical drive speed up A LOT, then it slows down, and ejects my CD, instead of running the setup. I became so desperate to get Windows back on my Mac, that I tried installing Boot Camp with my friend's XP SP 2 install CD. No luck. I thought my CD drive was damaged but it's not. For starters, the computer recognizes when I insert the XP & Vista CDs... it appears as, "XP_HOME_SP_2" with a CD icon on my desktop on the Mac side... In addition, I recently bought an external CD drive from Best Buy and I connected it and ran the Boot Camp install the same way and it actually mimicked my Macbook CD drive's behavior with both CD's... you could hear it speed up A LOT, then it slows down, and ejects my CD in the same fashion. I'm really glad I haven't lost my data, BUT this is putting me out of commission from a lot of my normal activities, so any suggestions or possible solutions would be greatly appreciated.
