Hello fellow peoples! I have an Acer Aspire E1-532-4870 from a woman who had upgraded to 10 some months back, and I have been trying to revert back to Win 7 for her. It was past the 30 days so I couldn't take the easy way out. When I first tried installing the Win 7 OS with the proper model-specific disks, during the setup it would say there was insufficient space on the disks for the temporary files. So then I deleted all the partitions and used a Win 7 universal install disk, which made all the partitions again for me nicely, and I was then able to put the model-specific disks in and install from there in order to not have to go through the bother of installing all those drivers. After the install went through the computer restarted and came up with a screen saying this: "Media test failure, check cable" and "No bootable device -- insert boot disk and press any key". I have checked the hard drive -- it is in very well -- I even cleaned it with special gold contact cleaner, to no avail. I am able to get to BIOS where I noticed that under HDD password it says frozen. I have no idea whether that is related to the computer not being able to see the hard drive or not. I did a hard reset on the computer and checked and after that it will say the HDD password is clear, but only for that one boot, and it still says it can't find the media. I even tried making various passwords and then clearing them to see if that would clear it up but that didn't work either. I tried doing a hard reset and then reinstalling 7 while the HDD password was clear, but nothing doing. Obviously I'm grasping at straws here. If anyone can assist me that would be greatly appreciated!
