Reboot and select proper boot device / Installing EFI bootloader

[RandomSquirrel]

hi,

 

i've installed yosemite on ASRock H87M Pro4 H87 + Intel Xeon CPU + Samsung SSD + R9 290 GPU.

 

however, i can only boot via usb. whenever i select my ssd, i get "Reboot and select proper boot device" as an error.

 

this is my disk-config (i plan to install windows 8 alongside os x, so just approx 120gigs instead of the 240 for os x):

/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *240.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Yosemite                120.0 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

 

this is the efi-structure

 

my uefi is set to boot from ssd as first priority.

 

anyone got any idea what's wrong here? like i said, everything runs smoothly (apart from some gpu and audio issues, but i'll tackle that later) when booting from usb.

 

thanks.

You already formatted EFI in FAT32? Follow this: UEFI multi boot with Clover

[RandomSquirrel]

Yeah, I used the sudo newfs_msdos -v EFI -F 32 /dev/diskXs1-command for the EFI-partition. But w/o the pendrive it doesn't load Clover.

[Allan]

Have you taken a look at the guide that I sent you?

[RandomSquirrel]

Yes, I did it exactly as described there.

 

sudo newfs_msdos -v EFI -F 32 /dev/disk0s1

mkdir /Volumes/EFI
sudo mount_msdos /dev/disk0s1 /Volumes/EFI

cd /Volumes/EFI

mkdir EFI

rsync -avh /Volumes/USB/EFI/ ./

 

+ Reboot & "Add as UEFI boot option"

[Allan]

You received any message of errors?

[RandomSquirrel]

Damn, now that you mention it... sorry: "warning: /dev/disk0s1 is not a character device" shows up after formatting the EFI-partition. What's that supposed to mean?

Open Terminal and type: diskutil list

 

And post here.

[RandomSquirrel]

I already posted that in the OP, but here you go:

 

➜  ~  diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *240.1 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Yosemite                120.0 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER

OK, sorry.

 

Try download Clover and install in EFI. Just remember to unmount the EFI before install Clover.
