Hi, I upgraded from Windows 7 to Windows 8 Pro at the beginning of the year and all was ok. However, I did notice my PC crashing overnight about once every couple of weeks and I'd have to re-start it the next day. It still then fired up into windows 8. However, about a week ago it started crashing everynight. it did boot to windows a few times but then it started to auto repair when I re-booted in the morning. The repairs did not work and with the Windows boot disc I couldn't upgrade again so decided to go for a complete fresh install. I have 2 disk drives on the PC. 1GB which is my main c: drive and where I originally installed Windows 8 and 1 170MB drive which I just used to copy things too. However, when I selected "custom" and "Drive 0" (which is my 1 GB c drive) it goes to the next screen and just hangs.. the "Copying Windows Software" stays at 0% and after about 10 mins I get the message saying it cannot access drive 0. I've tried this a number of times and even when I select Drive 1 (my 170 MB drive to install Windows 8 on instead) I get the same Drive 0 error. I'm not technical but have looked at a number of forums. I've installed Linux Puppy and used Gparted to try and re-partition the drives. this works ok for the 170 MB drive but the 1 GB errors and it cannot be re-partitioned. or formatted. I've also accessed the DISKPART tool on the command prompt.. did the "Create Partition Primary" for the 170 MB drive and then formatted ok gave it a d: letter. tried the same for the 1GB drive and it failed with a "The Parameter is incorrect" message. Not sure if this is the issue where there's a recovery partition on the drive as the original Windows 8 install was on this drive but I can't see it in any of the tools. I have also seen elsewhere that it could be on the "a: drive". I don't have a floppy and I can't access this in the command prompt but in Gparted it says there is an a: drive that's mounted.. I have then unmounted this, done all of the above again and it still doesn't work. Any help greatly appreciated! thanks. NGT.
