Hey guys,

So as the title says, I am looking to install Lion on my netbook. I have already made the USB, but my installation attempt stalls when i boot the laptop and OS X doesnt load past the white screen with the Apple in the middle. Any ideas? I'm trying to get this working ASAP, so please let me know if you can help.

You need a patched kernel with the Atom CPUID. Use the next bootloader: http://osx86.co/f36/new-bootloader-for-lio...-made-by-t7178/
Read carefully the thread.

Hi, thanks for your response. So I read the entire thread, and understood none of it to be quite honest. I downloaded the modified files, and then placed them into the appropriate (I think) folders on my Lion USB. Everything in the modules folder was placed into /Extra/modules, and all of the other files were just placed into the root of the USB. However, I cant even get the USB to show the Apple anymore. My netbook tries to boot from the USB and instead moves on the boot from the HDD. Any ideas?

You only need copy /Extra/modules and /boot to usb. When you boot your usb, you should see a boot list when you can select boot your pendrive, this behavior can't occur if you have a prepared /Extra/com.apple.boot.plist so you should delete that file.

PD: It's more interesting init with -v flag, apple logo doesn't say nothing

Okay, so I have gotten the chameleon bootloader to work, but when I try to boot it fails shortly after starting... I tried to see the error in verbose mode, but the system restarts too fast for me to read the error line. any ideas now?

Use flag arch=i386

Could you select drive to boot in Chameleon?

Did you press enter key because the boot process stops at certain moment?

If you use flag Wait=Yes, you will see all log before boot to drive.

I have the HDD turned off in the bios, because chameleon will not load otherwise, even if my USB stick is at the top of the boot sequence. And the only time i press enter in the whole boot sequence is after i enter the flags ("-v arch=i386 Wait=Yes") but it still instantly reboots. The last thing I can see it printing before the reboot starts with HFS+ and says something about mach_kernel. But i cant see the specifics.

I believe that you haven't the bootloader installed correctly. With Wait=Yes you must press enter key before init mach_kernel. Try copy all to USB again and remember copy boot file to USB from the indicated bootloader

Toshiba Mini NB255-N245 10.1-Inch Netbook, integrating the power of Intel Atom N450 processor and NM10 Express chipset with a six-cell battery for up to 8.3 hours of battery power, you'll be able to enjoy your school-day, work-day or errands without worrying about a recharge. Toshiba Mini NB255-N245 10.1-Inch Netbook also boosts performance somewhat and retains the wide responsive trackpad, and the systems battery life and hard drives are definitely below average.

Toshiba Mini NB255-N245 10.1-Inch Netbook comes pre-installed with the Microsoft Windows 7 Starter operating system, which combines the latest in reliability and responsiveness with the familiarity and compatibility of Windows.

Sorry to bump an old thread, but I have a Toshiba NB255 netbook. It has trouble booting from external media (it won't do it at all) if QuickBoot and other BIOS speed improvements are turned on (which they are by default). If you turn all the speed improvements off, if will only boot from standard flash drives. I can't get it to ever boot from a SanDisk for example.

I have to do this every time I install Ubuntu. Then I just re-enable the speed improvements when I'm finished with the flash drive. Kind of an odd quirk if you ask me.

EDIT: I went into the BIOS, and on the Main tab is a Boot Features section. In there, you want to make sure "QuickBoot" and "Fast Boot" are both disabled. Hope this helps!
