Suppose you’ve got one of the new Macs, with an Intel processor, and want to install Windows XP to dual boot, using the nifty new tools that Apple released today, but you notice that they say you have to have a full XP disc, and all you have is an upgrade disc? Is all hope lost?
I’ve been doing some reading on this requirement. The reason for it is that there isn’t a way to eject the CD during the install, and so, if you are using an upgrade disc, you are screwed when it asks to see proof that you are entitled to install the upgrade.
A possible solution is to burn a new XP install CD that merges your upgrade CD and the CD that you would use to prove eligibility for the upgrade. This turns out to be fairly easy. This turns out to be fairly easy. I’ll use the Win98 CD as the proof CD, but something similar should work for other possible proof CDs.
These instructions assume you are on Linux. (If you don’t have Linux handy…it’s only a live CD away).
1. Make a directory, newcd, and copy everything from your Windows XP CD to newcd.
2. In newcd, make two subdirectories, named drivers and win98.
3. Copy all the files from the win98 directory on your Win98 install CD to your newcd/win98 directory. You do not need any of the subdirectories of win98, just the files.
4. You need to grab the boot image from the XP CD. How to do that is described at himinbi.org. Save that boot image as newcd/boot.img.
5. Make an ISO image of newcd:
mkisofs -relaxed-filenames -d -D -l -N -o newcd.iso -b boot.img -c boot.cat -no-emul-boot newcd
6. Burn newcd.iso to a disc, using your favorite ISO burning software.
You should now be able to install without having to swap discs. This is still the upgrade edition of XP, so it will ask for proof of eligibility, but you can just hit ENTER.
BTW, when it is checking for proof of eligibility, it doesn’t necessarily look at the contents of the files in the win98 directory. It just looks at the names. So, if you want to save space on the disc, say to make room to slipsteam SP2 in, you can try this:
for i in *
That will truncate each file to 0 bytes. Do that before you make the ISO image.
NOTE: Here are instructions for slipstreaming SP2.
NOTE: I have now had a chance to try a disc made according to the above instructions, from an upgrade Windows XP Pro disc + a Windows 98 disc + slipstreamed SP2. It installed fine on my 20″ iMac, and I’m typing this from Windows right now on that Mac.
UPDATE: An 80 min CD-R is big enough to allow you to skip truncating the files from the win98 directory.
