Cannot boot into boot menu from GPT-formatted hard drive
I have acquired a new laptop, a Lenovo ThinkPad T420. I got everything working beautifully, but I cannot boot into the system from the hard drive itself. The boot menu never comes up, whether I use GRUB2 or Syslinux. I can, however, boot from a Linux install CD or thumb drive and select the "boot from existing OS" option, which takes me straight to the GRUB2 or Syslinux boot menu.
Initially, I was going for making this a UEFI system. So I formatted to GPT, added the UEFI partition and installed GRUB2, which reported successful installation. However, the GRUB2 boot menu would not come up. I could boot using a CD or thumb drive and choose "boot into existing OS". I reinstalled GRUB2 several times, to no avail. So I discarded the UEFI option, created a GRUB2 bios partition and did the grub_bios-install. This also reported success, but, again, it did not boot. Lastly, I installed Syslinux (also into the MBR). Same problem.
Parted gives me this:
Model: ATA WDC WD7500BPKT-0 (scsi)
Disk /dev/sda: 750GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags
1 2097kB 204MB 202MB fat16 UEFI
4 204MB 206MB 1049kB BIOS boot partition bios_grub
2 206MB 357MB 151MB ext4 BOOT legacy_boot
3 357MB 750GB 750GB LVM lvmAny ideas?

Re: Cannot boot into boot menu from GPT-formatted hard drive
"However, the GRUB2 boot menu would not come up" - What exact error(s) are you getting? Any idea on http://www.rodsbooks.com/gdisk/bios.html for grub2-bios or syslinux. If you are able to work out UEFI boot, stick with it since GPT works best in UEFI system.
