ZERO16LIVES Posted September 24, 2009 Share Posted September 24, 2009 Ok, so here's the situation. I have been trying to install OSx86 for a long tome now. I finally found a guide that worked. I used a Leo4Allv4.1 disk with a special Extensions.mkext injected into it. It saw my hard drive but only recognized 120-something GB of it (of 149 GB) because of the kext that was used. No problem I shrank my windows partition and made a small partition at the end of the 120-something GB to install OSx86 on. I figured I would extend the partition after it installed. Unfortunately I found that OS X can't extend a partition that's on a MPT disk. So I decided I'd make an image of my install with Norton Ghost 12 (which I've heard is one of the few Ghost versions that can image HFS+ partitions.) I used Windows to format the free space at the end of the drive then formatted the partition to HFS+ in OS X. Then restored the image to the new partition, deleted the old, extended my windows partition, and booted into Mac OS 10.5.4. Now the problem. OS X listed about 600mb free space, 26gb total, 7gb used. Oh no! So I open disk utility. Click "Verify Disk" ("Repair Disk" was greyed-out) It failed and said "Invalid B-Tree Node Size." I also tried it in safe mode, same thing. I searched Google a lot and found nothing that would help me. Except for one thing about disk warrior. I downloaded and installed it but it said it can't fix a volume it's installed on or that your booted into. So I started burning it to a disk and when it was almost done it remembered that my pc can't boot a Mac disk. Now I don't know what to do. I don't know if it will help but I've attached a CPU-Z report. Any help is appreciated.

srs5694 Posted September 24, 2009 Share Posted September 24, 2009 A few comments/suggestions: There are OS X emergency discs available, both as downloads and as procedures to build your own. You can use one of these as an emergency system. You can use your install disc as an emergency disc, but only in a limited way. When you get to a point where a menu bar is visible, find the item to launch a terminal. That'll give you a shell (text-mode) access to the system. You can use this to run text-mode and even GUI tools, but you'll have to locate the actual executable component for the latter. Using one of the preceding methods, you could try the Disk Warrior tool you mentioned (I've never used it myself). Using one of the preceding methods, you could try using Carbon Copy Cloner or some similar tool to back up your corrupted OS X partition, then reformat the partition and restore the backup. This will require that you have access to a big enough "scratch" disk, though. There's a Linux fsck.hfsplus utility that does checks on HFS+ volumes. You could try running it from a Linux emergency disc, such as System Rescue CD. (I've not checked that fsck.hfsplus is actually available on that disc, though. If it's not, you'll need to track down a binary and put it somewhere that System Rescue CD can read it.) I don't know how good or reliable this utility is, though; it's conceivable it will make matters worse. Best of luck with your problem!

ZERO16LIVES Posted September 25, 2009 Author Share Posted September 25, 2009 Thanks for the suggestions, I think I fixed it. I shrank my Win 7 partition, and formatted it as fat32. Then booted into osx and formatted to hfs+. Then Ran DiskWarrior from the new partition. It appears to have worked, Disk Utility lists 19gb free space now EDIT: I did work *LOCKED* EDIT2: No lock topic here?
