Hello

I have installed Fedora 18 on a HP envy h8-1520t(EFI system). I could only get it to install/boot with secure boot disabled.

However the bigger problem is that if SATA emulation in EFI is set to "ahci" (as opposed to "ide") it hangs with the message "Loading inital ramdisk" The installation was done with SATA emulation set to "ahci". But it will boot if I set "ide"

AND it will boot with SATA emulation set to "ahci" IF AND ONLY IF a usb pendrive is plugged in. When it boots as such,

So ahci support is in the kernel.

Also, grub does not recognize any of the partitions except for the fat16/32 efi (windows and linux) partitions.

grub> ls

(hd1) error: failure reading sector 0xfc from `hd1'
error: failure reading sector 0xe0 from `hd1'

There is only 1 hard drive on the machine.


grub>ls (hd0,1)
error: unknown filesystem

grub>ls (hd0,2)
efi/

grub>ls (hd0,3)
error: unknown filesystem

grub>ls (hd0,4)
error: unknown filesystem

grub>ls (hd0,5)
error: unknown filesystem

grub>ls (hd0,6)
efi/ System/ mach_kernel

grub>ls (hd0,7)
error: invalid file name

grub>ls (hd0,8)
error: unknown filesystem

I ran that bootinfoscript, but it uses fdisk and this disk is partitioned GPT not MBR so I'm not sure the results are reliable.

I'm told by the extremly unhelpful HP support that this is a Pegatron-IPMMB-FM motherboard and I know the EFI is made by AMI. Apparently no firmware updates are available. The tech support had no idea what I was talking about when I asked.

It'll be the last time I get one of these boards and most likely any PC's from HP.


Any help would be appreciated.
