|Its possible that your CD/DVD rewriter optical is out of sync. |
I've read that DVDs typically do not work and you need to use CDs. With Compaq, it seems they require between 5 & 12 disks.
#1. Try installing another CD writer.
#2. Enter into Safe Mode and do the recovery from there.
#3. I have Recovery Disks for Compaq Models: SR1020Z, SR1030V, SR1030Z, SR1601NX,SR1602HM, SR1603WM, SR1610NX, SR1611NX, SR1614X, SR1616NX,
SR1617CL, SR1620NX, SR1630NX, SR1638NX
I'd be willing to sell them for $35 (including shipping)
