I am trying to install Snow Leopard on a Macbook from 2006. It's turning out to be more of a challenge than anticipated, so I'm hoping someone here can help :)

Snow Leopard is on a dvd, but the internal dvd drive of the Mac isn't working properly and gets too many read errors to install it properly. Got an external drive instead, but for some reason it only reads the Windows side of the disc (whereas it reads some other Mac discs just fine..). So I used the disc utility on another mac to create a disc image of the dvd and then copied that to a usb stick.

I then read some instructions online and realised I had to make the USB stick bootable, so I did that and copied the .dmg back to the stick, but I cannot get the stick to show up on the boot menu (the windows partition shows up fine).

So then I tried instead to make room on the mac (the hard drive is a bit full) to copy over the .dmg file and run it from there, but to no avail. So I figured I have to 'restore' the .dmg file first with the disc utility, but it won't let me drag a volume to the destination path. I can only drag a volume to the source (without problems), but it won't accept anything in 'destination'.

What can I do to install from the .dmg file? Do I need to make a new image of the dvd to copy onto the usb? I've tried going through install guides from the web, but I keep running into issues like those listed above..

The restore function is the correct path. You have to do a restore function on the USB stick to make it bootable. Copying it to the USB stick is simply a file copy; restoring it is what makes it bootable. Here's a tutorial:

Drag the DMG to the source (copying from this) then drag the volume name to the destination (copying to this). If the DMG won't copy over, try mounting it (double-click the disk image). If the volume won't copy over, try dragging over the partition sub-volume (the indented one with the name, such as "Hard Drive").

Thank you, I will try that again. The problem was in fact with copying the volume over.
