[MOOT] Can't access bootloader in laptop w/out chainloading (syslinux)

Question

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).

Answer 1

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.
