Nawcom's latest Boot CD – allows MBR installation

With the latest work of meklort , whereby he has created a way to patch OSInstall.mpkg on the fly – which allows you to install OSX to a MBR partition , which means that you don’t have to format the entire drive to GPT in order to install OSX. This should be pretty good especially if you want to keep your recovery partition or your current windows partition and would like to install OSX along side with Windows. Nawcom , on the other hand sliced it alltogether and created a boot CD for you to test it out
Bear in mind that , this is still experimental. I am not responsible if your computer blows up , if an alien abducts you , or if your PC wets the floor for some odd reason.

  1. Hey! I tried this and it allows me to install with a Core i7 980X and an nVidia GTX 470 installed! It loads a 64-bit kernal, too! It’s limited to 1024×768 resolution but I can boot from EasyBCD which I couldn’t do before. If there’s ever a driver for the GTX 470, I’ll be all set. Thanks Nawcom et al!

  2. meklort has been using it in his NBI installer for a while, he would take advantage of folder the WindowServer binary. I edited the source code for the PostBootMounter kext so it takes advantage of the /etc folder instead, so i can do the on the fly modding of the files via a modified rc.cdrom script. I might update the source code so the mount point can be easily controlled from a boot flag or plist entry, but for now if anyone wants to use it in a different location you have to modify the source code yourself.

  4. I’ve tried all the efi swap iso’s i can find and on all of them once the Mac OS X cd pops up after pressing F5 and continuing, its stops working and restarts my computer.

  5. @Nawcom
    I’ve heard that EmpireEFI will be getting v2.0 soon…
    Any plans on incorporating this into your bootcd?
    Also, I heard a rumor you have a version for 6 cores?

  6. I’m not having your level of success. Whether usb (stick or disk) or cd/dvd, I hang at “Reading HFS+ file [(rd0,1)/Extra/smbios.plist 421 bytes” and there’s also a constant reference the line previous to not being happy with the DSDT.aml file.
    I’ve been close enough to have the mbr disk with xp/ntfs, chain0, and snow leopard sitting there, but haven’t found a boot file nor a boot1h file and plist to make the setup happy.
    Using a standard Dell 1011/10v, but I want it mbr and dual booting, and it’s been teasing me and won’t do it.
    Love to buy a clue,

  7. Nawcom has posted a response to my questions regarding his new bootcd, but I could not follow up since my office G4 had crashed, and I had a major project due last week.
    For nearly a week, his website has had a message posted that he is going through hardware upgrades.
    I wanted to know if there was a way that I could get his postings from his website so that I could attempt to use his bootcd with my computer that hung with a kernel panic?

    Sorry if this e-mail and its requests might be off topic, somewhat, but do not know how else to attempt to contact nawcom while his site is parked.

  9. Hallo, after installing os x retail snow leopard with nawcom, what do i need to do to boot the os x with out the nawcom cd, please teach me. I have istalled the dsdt from nawcom downloads

  10. I could not get it to work. Kernel panic error. I cannot find a place to set AHCI in the BIOS of my rig which is an i7 with an ASUS P6T motherboard, intel chipset X58. Any ideas?

  11. Inspirion N5010 i3 350m 3gb ram ati 5470. AHCI / Virtualization set in bios but i get the kernel panic… 🙁 -> The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point. “unable to find driver for this platform \”ACPI\”.\n”@/Users/Build/xnu-1456.1.26/iokit/kernel/IOPlatformExpert.cpp :1393

  12. I’m new to this topic, and first of all: how can one achieve the skills needed for this great work?
    second: I wonder if there’s a chance installing osx from a OSX retail dvd copied on a guid partition on a usb-drive? This worked on my macbook, because you can just choose the partition you want to start from.
    third: are there any experiences with dell precision m4300, for I couldn’t find any through googling

  13. Cet iso est le seul bootloader qui m’a permis enfin d’insaller SL 10.6.3 sur une Gigabyte GA-X58A-UDR3 (rev 1.0 Bios F6) sans aucun problème. Je voudrais maintenant savoir s’il y a un moyen de ne plus booter sur le CD afin qu’il démarre directement sur le disque dur. Merci d’avance

  14. Hola a todos, he probado nawcom bootcd; pero no funciona en un hp g42 con core i3, inicia el gestor de arranque pero cuando pongo el cd de snow leopard termina de cargar los kexts y se reinicia, no se que es lo que pasa.
    Si alguien puede traducirlo al ingles correctamente lo agradecere.

  15. Hola Igor, voy a traducir tu post
    Im translating Igor’s post, im having the same issues as him, i also have a HP G42 Laptop, i eject the boot cd, insert the OS X and fire it up, but whrn it says “press any key to continue” the computer just reboots, any solutions pradeesh?? nawcom???

  16. hope you could help I installed with the newest nawcoms cd that came out in dec. install went fin, i rebooted, it load the boot loader chameleon and then i get a loud fan like it at 100% and also 1 long 2 short beeps from the pc speaker which I know is video and and when that happens my screen go blank, anyway to fix or get in to fix this? Thanks Sorry for being harsh before 🙂

  17. I tested version 0.3.1 on my AMD Phenom X4 9950 BE on a Gigabyte MA78GM-UD2H and Geforce 9800 GT: everything was recognized.
    The problem is my other PC: SN78SH7 Shuttle barebone (Geforce 8200 chipset) and Phenom II X4 955 (3.2 GHz) and I get a kernel panic during booting the retail DVD, telling me the rtc could not determine FSB correctly and causing a kernel panic. I know my system should be Mac compatible since there is already a working installation using the Leohazard 10.6.2 method (upgraded to 10.6.6), but I want to know what causes this kernel panic problem to help Nawcom to improve his boot CD.

  18. I have a Sager NP7280 which is built on a Clevo 7200X. This computer (a laptop) has a intel i7 950 clocked at 3.20GHz (desktop processor in a laptop) it has 12Gb ram 2 NVidea 460M graphics cards and 3 500gb hard drives. I have been trying to install mac os x on this computer. I have been using mawcom’s boot cd. No matter what boot options i set
    -v -x -s -f busratio=23 CPUs=1 
    I have tried all of the both both together and separately. It causes a kernel panic right after it asks me to press and key to continue. This is the error that it gives at the top of the kernel panic
    Panic (CPU 0 caller 0x27a9ba): “pmap_steal_memory”@/Users/mawcom/builds/xnu-1456.1.26/osfmk/vm/vm_resident.c:744
    Any help with this issue would be great thank you in advance

  19. Hi,
    I’m having issues. I am trying to install osx on my samsung n150 plus. It allows me to boot to nawcom boot cd. After it loads, i put in the retail os x dvd 10.6.3 hit f5 then enter. It will start to run then I end up with: the kernel panic occurred. We apologize for the inconvenience. At the end of the whole lot of things there, it says: system uptime in nanoseconds: 1274646537. Please help.
    Thanks

  20. Nawcom ModCD and 10.6 install without a hitch. But, when I reboot it says I need legacy kernel. I’ve downloaded the legacy kernal-10-1.6.0 pkg, but don’t know how to install it since I can’t get into Mac.
    This is being attempted on Satellite L505 with Core Duo 2.
    Any help will be appreciated, Hozey

  21. Is there any way to get this to work on an AMD Turion processor? I’ve tried, but no luck. Nothing else, I’ve tried them all I think, works.

  22. Has anyone got this working with a GTX470 with a res other than 1024×786. I noticed other flavors of osx on pc claim to have gtx470’s 480’s working with osx on pc but what is not clear is weather they are talking about just getting one of the new fermi’s working @ 1024×768 or have they got them working with all the res options available up to 1080×720.

  23. @Tom Lake I read on nawcoms blog you have a GTX470 working with this osx using the “new fermi drivers”. Can you tell me are these the ones from Tonymac86 or if not which ones did you use. A little info on how you got it working would be appericated 😉

  24. Anyone getting a kernel panic with pmap_steal_memory issue (such as Jeffrey), I figured out how to fix it. Remove -x from boot. It is caused by safe mode for some reason. I just put -v and pressed enter and it booted fine. Tested on my Alienware M17x R2. i7 940XM, 8GB RAM, 2x320GB, Dual 5870M in CFX, 1920×1200 RGB LED…

    I forgot to delete the sleep kext had kernel panic.. then had this problem above when using the cd.. then while it was already crashed i overrode the CD lock on VMware to put the mac osx cd in and all of a sudden i was booted and on my desktop instantly.. can’t even explain how

  27. Aw, this waas an exceptionally nice post. Taking a ffew minutes andd actual effort too
    generate a great article… but what can I say…
    I hesitate a lot and never seem to get anything done.

The main emphasize on the security check has lead to making such IP stressers a big hit lately by 2018. Companies making the business of million dollars each hour are usually running on much complex system and they time by time need to do stress testing under real traffic conditions.
