 |
|
Greetings, Gentoo users!
I'm trying to boot Gentoo from USB from my MacBook Air 4,1, but the booting process is getting to a point where it says "Could not find the root block device in .", without any other error, then tells me to provide it manually or enter a shell.
Where is the root block device so I can mount it manually?
Thanks!
P.S. I've noticed there exists a file called image.squashfs on the USB stick which apparently contains a root filesystem, but when I mount it then point to it when it asks me for a root filesystem, it says invalid root filesystem. |

Your steps above are obsolete with the current install media and livedvd. The minimal-installcds can be usb bootable by running | Code: | | # isohybrid image.iso && dd if=image.iso of=/dev/sdb bs=8192k |
and the livedvd can just be dd to the usb device as so | Code: | | # dd if=image.iso of=/dev/sdb bs=8192k |
Hope this clears confusion as http://www.gentoo.org/doc/en/liveusb.xml should be avoided, but just so you know that if your Macbook Air uses UEFI neither install media will work since isolinux's isohybrid doesn't support UEFI and the install media uses isolinux bootloader which is not UEFI compatible. |

You will have to use a linux livecd that supports UEFI, we currently don't support this. |

| EFI support for isolinux will come with syslinux-4.06. |
