Your story has been told before so here's the answers (and they are repeated so you can get it working again as fast as possible.)
1. Order the restore media.
2. Order or borrow the required USB DVDRW drive.
Again, this has been covered numerous times. And you write you have 10 computers so why isn't some USB to DVDRW cable an option here? It's cheap too. Example at:
Even the entire drive and such is not bad. Example at:
Hi, do hope someone can help!
When I tried to start up 'puter this morning, all icons except a few had turned into non working ones, system restore failed to initiate as well as explore & all the other .exe files. Started up in safe mode, couldn't restore. Panicked & went into advanced recovery thinking I had a back up or image (I have about 10 computers & I think this is the only one I didn't have the back up on)! Now, it tries to boot but then suggests 'system repair' but it won't fix anything & Windows won't start. It comes up with Windows 7 logo, but that's it! Now, I don't have a cd rom drive, only usb ports. Haven't got any boot disks as I only bought it recently upgraded to Windows 7 from ebay. Was working perfectly for 4 months & now I've stuffed it up. Can somebody please help me with any suggestions???
