[syslinux] Booting with Syslinux 6.01 & 6.02 fails, causes restart.
Hi there. I had a quick look through the archives, and I spotted a similar issue being reported in October, but no resolution, unfortunately. "[syslinux] Syslinux 6.02 BIOS" I am booting in legacy (bios) mode on a gpt partition on my laptop. It's a HP ENVY dv7. CPU: Intel i7, BIOS: InsydeH2O version: F. 12 With syslinux 4.06, it boots flawlessly. With syslinux 6.01 and 6.02, the welcoming message flashes up, then the automatic booting of the first initramfs. It's a rather large initramfs. Straight away the booting process looks different than with 4.06. The periods that were showing progress in loading the initramfs now does not increase as the initramfs is loaded. So, only three periods after each initramfs. Once the last initramfs is loaded, the system re-starts. This process repeats about six or seven times, then the kernel loads.. but only when booting from an internal hard disk. If I try booting through syslinux 6.02 installed on an external USB hard disk, it just carries on loading the initramfs, then rebooting for about ten times, then then it just constantly reboots, shows the automatic boot window, and reboots again. What information do you require from me to help with troubleshooting? Syslinux was compiled from sources on my laptop, and I am quite happy to try patching the source code if someone has an idea to try. Any help would be greatly appreciated. On a side note, I have a video clip of the faulty booting, as I was trying to see if there is an error message I am missing, but none was apparent. It's possible for me to post this clip on youtube and post a link here if anybody is interested. -- Evert Vorster Chief Observer WG Cook

This detail seems missing but your reference seems to indicate possibly. bios/core/pxelinux.0 or bios/core/lpxelinux.0? Did you use the precompiled binary right after extraction with no make commands? -- -Gene

However, some sort of indication that the initramfs is loading would have been nice. Solaris uses a spinning cursor, for instance. But, this is not important to the current issue.>> Once the last initramfs is loaded, the system re-starts.This is the bit I am having a problem with.> Are you also doing PXE booting?

I am trying to boot a volume that has been partitioned with gpt. It has a legacy bios boot bit, that is set active. As I said before, with syslinux/extlinux 4.06 this works flawlessly.> bios/core/pxelinux.0 or bios/core/lpxelinux.0?

Then I installed with extlinux --install -s /boot and then copied in gptmbr into /dev/sda and re-created the initramfs bundle that this distrobution boots from . Then rebooted. Thanks for the quick response. -Evert-
