My laptop is Acer and I burned 4 backup CDs for recovery purpose. Later on, I created folders Acer 1, Acer 2, Acer 3 and Acer 4 in my USB HDD and I wrongly just copied and pasted from these 4 CDs to each folder in my USB HDD instead of making CD images. And I don't have these 4 CDs with me now. Also my laptop got problem, so I want to reinstall my OS. But I don't have 4 of my backup CDs. So I burned another 4 CDs from my USB HDD as data CDs. Because of being data CDs, it didn't work out. So I again burned my first backup CD as a bootable CD (I just burned as a data CD and made as a bootable CD). I can boot with it, but it doesn't automatically install OS and all of the software and driver (because it's supposed to install OS and driver automatically, and I just need to insert CD 2, 3 and 4 right?). My problem is that it booted, but did nothing. It appears "A:>" and cursor is waiting after that. I wonder how I can get the CDs that I had. Now I don't have 4 original recovery CDs and I just have backup files in my USB HDD that I just copied and pasted". Please tell me how I can burn from my USB HDD to get 4 recoverable CDs that I had.
