0.8.1, OS X: Unable to mount ESP

[Anonymous]

Hi! That's what I get when trying to install to my ESP (because I use WDE):

XXX:refind-bin-0.8.1 xxl4232$ diskutil list

Unable to mount ESP! Aborting!\n

Edit:
I can mount it manually

How did you mount it manually? Some people have HFS+ "ESPs," which would explain your symptoms. (I put "ESPs" in quotes because ESPs, by definition, use FAT, so it's not really an ESP if it uses HFS+.)

Thank you for your reply! Here's what I did:

XXX:~ xxl4232$ mkdir /Volumes/esp
XXX:~ xxl4232$ sudo mount -t msdos /dev/disk1s1 /Volumes/esp

I just checked the format; it's FAT32.

As one can see in the diskutil list above, I have a second internal SSD (disk0) instead of the dvd slot drive. Could this cause problems? Its EFI-partition is empty.

There's a bug in the MountOSXESP() function in the Install.sh script which makes it not work when you have more than one disk with an EFI partition.

[joevt]

In the Install.sh script replace the line:

Temp=`diskutil list | grep " EFI " | grep -o 'disk.*'`

with this:

Temp=$(mount | sed -n -E "/^(\/dev\/disk[0-9]+s[0-9]+) on \/ \(.*$/s//\1/p")
if [ $Temp ]; then
    Temp=$(diskutil list $Temp | sed -n -E '/^ *[0-9]+:[ ]+EFI EFI[ ]+[0-9.]+ [A-Z]+[ ]+(disk[0-9]+s[0-9]+)$/ { s//\1/p
            q
        }' )
    if [ -z $Temp ]; then
        echo "Warning: root device doesn't have an EFI partition"
    fi
else
    echo "Warning: root device could not be found"
fi
if [ -z $Temp ]; then
    Temp=$(diskutil list | sed -n -E '/^ *[0-9]+:[ ]+EFI EFI[ ]+[0-9.]+ [A-Z]+[ ]+(disk[0-9]+s[0-9]+)$/ { s//\1/p
            q
        }' )

    if [ -z $Temp ]; then
        echo "Could not find an EFI partition. Aborting!"
        exit 1
    fi
fi

Should the q characters be alone on a line by themselves like that? (sed newb question)

[joevt]

The script works as is with the q on the next line since the sed command is using single quotes. I think it also works if you wrote it using semi-colons like this

{ s//\1/p;q; }

The first line finds the partition containing root. If it exists, then it searches that disk for the first EFI partition, otherwise it looks at all partitions on all disks and returns the first EFI partition found.

Thank you very much!
