Unable to boot linux partition

#1
Hello!
My configuration is the following: 2 HD, on the first one a single partition with Win/, on the second one a NTFS partition, then two linux partitions, with Ubuntu 10.04 installed on the first one (bootloader on the partition itself).

I have tried to get EasyBCD working, but to no avail. I keep getting the error 0xc000000f, "\NST\nst_grub.mbr The selected entry could not be loaded..."

My debug setting is:
