I'm asking because I'm trying to install an uncommon version of Windows (XP MCE) on an OEM HP PC using an OEM build of Windows that was not intended for this model. It's a slow and pain-staking process to figure out the correct iso directory which will install fully, and I've burned about 5 ISOs thus far onto a single CD-RW and now I'm getting errors. I will probably have to burn a few more, any ideas how many times each CD is good for before it starts slipping?
