Razor1973 Posted May 31, 2008 Share Posted May 31, 2008 New to the project, never touched an Apple in my life. I did some reading on here and on lifehacker.com before I went ahead with the install. I have a Compaq SR1750NX with an AMD Athlon64 3500+ CPU, so I went for Zephyroth's 10.5.2 DVD. I had 2 hard drives, one with XP and one with Vista and a dual booting system. I then installed a third drive and installed Leopard on it as to not mess up my Windows drives. Install went through and finished successfully. And then the first problem happened. As soon as I tried to boot from my Leopard drive, I got the blinking cursor (messed up MBR?). I read some more and ended up trying to follow the instructions shown here. I did not know which one was my new drive, but I saw I had drive1, drive2 and drive3, so I figured this was the third drive, so drive3. However, as soon as I tried to do "dd if=./guid/boot1h of=/dev/rdisk3s1 bs=512 count=1", I got a "Permission denied" error. I tried with rdisk3s2 and rdisk3s3 as well (no idea why I would have 3 partitions when I created only one [the default] when I formatted during install) with the same results. Since I'm new to all this, I have no idea what this dd command is and did not think it could damage a drive that wasn't formatted to be used by OSX, so I issued the same command against disk1 and disk2 trying to find one where I would not get errors (figuring that would be the actual OSX drive), and one of them worked (I don't remember which one). My Leopard install never worked even after 4 different attempts selecting different options during the initial customization, doing permission and drive repairs from Darwin, etc., but that's not the point of this thread. My biggest problem right now is that I can no longer boot into Windows. No matter which of the 3 drives I choose to boot from, I get the same blinking cursor. I am guessing issuing that dd command against all drives screwed my MBR and now I wonder how I can fix it. Once I have Windows back, I'll retake Leopard being more careful. Any advise please? Thank you. Link to comment https://www.insanelymac.com/forum/topic/107996-so-i-went-and-destroyed-windows-drives-mbrs-help-please/ Share on other sites More sharing options...

Razor1973 Posted May 31, 2008 Author Share Posted May 31, 2008 this happens if you have EFI an speedstep. ONly fix i found was to delete windows in Disk Utility and install iAtkos over it again. Even though I have seen both EFI ad speedstep terms while reading around here, I have no idea what either of them are or how they affected me. Could you offer more details on your recommendation? Deleting Windows, whatever that means, doesn't sound good.

edeseven Posted June 1, 2008 Share Posted June 1, 2008 hey razor try to boot using your vista dvd let it load, and select repair your computer option it will then find your vista partition, and select it after that, choose command prompt option from the list type: bootrec.exe /fixmbr and then restart your computer hopefully this will fix your vista bootloader guide: Vista bootloader repair For your leopard installation, to fix the bootloader, make sure you have the right partition selected. type: diskutil list and note the disk number and partition number from that list and then follow the guide you mentioned above hope it helps!!
