I have an Acer Aspire laptop that part of the time when it is turned on will boot into Windows 7, although it is pretty sluggish once in Windows. The other part of the time, when it boots it says that no bootable media is detected error. In the BIOS, it is set as hard drive first, and the BIOS recognizes the hard drive. If I remove the hard drive and plug it back in, the computer will boot into Windows one time, then back to the no bootable media detected error. I have also gone into the BIOS and told it to use the defaults. I took the hard drive out and plugged it into a hard drive doc on my desktop to copy files off just in case. When I clicked on my user name it took probably a good 10 minutes for it to show me the files/folders under my user profile. The hard drive is a 320 GB Toshiba SATA. Would you think the problem is the hard drive or the connector on the motherboard for the hard drive?
