[MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)
EDIT: Laptop died shortly into thread.
---
I've run into a curious error as I'm installing onto a new laptop for the wife (Acer Aspire V5-531). As in most laptops, it has a single hard drive.
I've gone through the install, and threw on syslinux as the bootloader. I reboot, pull the installation USB from the drive, and suddenly the computer tells me it can't find the OS (syslinux doesn't appear at all).
I've discovered though that if I plug back in the Arch install ISO, change the 'Boot into existing OS' option within syslinux to 'hd1' rather than 'hd0', I can chain load into my install of syslinux successfully and boot.
I've tried about everything I can think of messing around in the BIOS with boot settings, but I haven't the slightest idea why this is happening.
I'm attaching below the output of the popular bootinfo script.
My partition scheme:
sda1 - Windows recovery partition
sda2 - Another small partition that already existed with windows stuff
sda3 - Windows C:
sda4 - Extended
sda5 - /boot
sda6 - swap
sda7 - /
sda8 - /home
(sdb is the USB holding the arch install media).

Re: [MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)
You might want to start by re-installing syslinux - look at the notes in the "boot info" sda5 section of your boot script output

I see the supposed corruption there, but it doesn't make sense to me that I'm able to get it to work at all in that case, chain loaded or not.
At any rate, I have tried re-installing it a couple times now, and even using grub instead. It doesn't seem to help.

Re: [MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)
Went ahead and duplicated the results that I'm seeing using grub-bios this time. Same problem, and the same strange method of getting to the bootloader through chainloading works.

Re: [MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)
I think boot partitions must be primary. Your boot partition is an extended partition.

Don't think that matters... I don't use a separate /boot anymore - but my / is a logical partition.
@OP - Do you now want help with GRUB or SYSLINUX? Installing a 2nd bootloader without cleanly uninstalling the 1st is kinda asking for trouble and often results (as witnessed) in nowt but cold soup.

I'd prefer to use Syslinux. I'm just lost as to where you proceed.
I think I will format the Linux partitions and start fresh just in case I had missed something the first time. EDIT: I have now done so, and am indeed still having the same error.
I would appreciate suggestions of things I could try.
EDIT: I will also be hanging out in IRC if anyone would prefer to offer help in that way.

Re: [MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)
Well, now this whole this whole thing is moot: the laptop won't change anymore (and I've had it for 2 days). I'm returning it.
