|That looks to be one of those all-in-one boot cds that has some generic utilities and in this case some hardware drivers that emachines may use. It's not a recovery disk in the sense it would restore your original OS. For that you'd need the actual recovery disk from emachine or, as is common now, a recovery partition on the hard drive.|
I don't know what driver is not being installed but I suspect it may be a cdrom driver. I looked up the specs on that and it says you have a SATA hard drive. It didn't say if the DVD burner was SATA or ATAPI. If it's SATA there's only one dos driver I know that works--gcdrom.sys. If you have a SATA DVD then that's probably the reason. If you have a regular ATAPI DVD any cdrom drivers on the ebay disk should load OK as there are dozens if not hundreds of compatible ATAPI drivers.
Also, as I mentioned, you may have a recovery partition on the drive. Generally you change the boot order in cmos/bios setup to boot from that partition and then follow the instructions to reinstall your OS. Unless you have other problems you shouldn't need the ebay disk in order to use the recovery partition on the drive.
If you are looking to restore your OS you should probably consult your manual to check on the recovery partition and how to restore from there. If you still think you need the ebay disk try emailing the seller and since they wrote the disk they should be able to help.
