Macbook Pro & Windows 7 RTM – Select CD-ROM Boot Type
I decided today to upgrade my Macbook Pro to Windows 7 RTM. It’s been running the release candidate for some time now, with no issue. However when I came to boot from the RTM CD, I found a problem. This problem only seems to be related to the 64bit version on the Macbook, I believe the 32bit version is fine.
When you boot from the CD you’re presented with a CMD window that says:
1. 2. Select CD-ROM Boot Type:_
Obviously this is very helpful. Apparently this is due to the fact the Macs use EFI boot, which Windows 7 now supports, but the wrong version.
To fix this you’ll need a copy of ImgBurn to create a new Macbook compatible CD to use.
Essentially the process is:
1. Insert Windows Install disc into DVD drive
2. Using the build mode of ImgBurn, go to the advanced tab, then bootable disc and then select your DVD drive in the extract boot image drop down list. Go ahead and extract the boot image and store it somewhere on your hard drive.
3. Go to the information tab and add your DVD drive as the source file
4. Options tab, check that file system is ISO9660 + IDF and UDF revision is 1.02 (should be anyway by default)
5. Go to Advanced tab, sub tab Restrictions and further sub tab ISO9660: Set Folder / File length to Level X and tick the four check boxes at the bottom (allow more than 8 directory levels, Allow more than 255 characters in path, Allow files without Extensions, Don’t Add ‘;1’ Version number to Files. (Note it’s this bit that actually solves the problem the rest is effectively just duplicating the existing disc)
6. Move to the bootable disc tab: Click the tick box to make the image bootable, emulation type to “none (custom)” and the browse and select the boot image you previously extracted from the windows disc. Finally set Sectors to load to 4.
7. Click the big create iso button to create the bootable iso.
8. And use that iso to burn a new install disc.
This then booted fine for me.
Thanks to an excellent article by ‘Dangerous Dave’ to help solve this problem here.
