Install failed: USB is read only(?) - cannot find essentials.pkg

[anik]

Hello,

I've been trying to install Snow Leopard Retail using a usb formatted disk and applying myHack installer. I get to Snow Leopard installation screen, I get to about 25% of installation through and then I get the generic error 'the installer could not copy the necessary support files'.

The install log errors are:

URLForDirectory:inDomain:appropriateForURL:create: error:] returned nil for NSAutosavedInformationDirectory. Here's the error:

My Desktop PC setup:
-Intel Pentium Dual Core [email protected]
- Foxconn MB P43A01 with P45/P43 RevA3 chipset
- 2GB RAM DDR2 400MHz
- ATI Radeon HD 4770

- I have tried the installation with two different iso files of the retail dvd, just in case the image is damaged, but the same message comes up.
-I have also bought a new Hard Disk and created only one GUID partition, in case the windows partition-installation messed up with the installer. Again, this was not the case.
-BIOS settings should be correct, AHCI set, ACPI: S3(STR), etc, note that leopard installation boots.

I really would appreciate any help on this, I really need to get my Snow up and running! ;)

Thanks,
Alex

I have the same problem here, did you figure it out?

Try a different USB key. Make sure you verify the permissions of the USB key and the Snow Image, Although I would recommend buying the Retail Snow Leopard DVD and using that to make an image, or just buying the Retail Snow Leopard DVD and using the Empire EFI CD to install.

Thank you for your reply.
I think i found the problem, my graphics card is an ATI HD 4770, which is not supported at all. I'm getting a nvidia 9800gt and i'll try again..
