Re: double booting with iMac (bondie blue, rev 1)

Thanks for the input, my problem is fdisk tells me that the disk “has no valid signature” and shows the whole disk as unused. pdisk yields a similar input: “no valid partition map found on wd0 \ Create default map ? Y/N. The question is, will creating a default map mess up my entire disk now? I.e. If I type “yes” would I be able to boot Mac OS again ?
