What do you mean by "lost"? It doesn't appear on GRUB's menu? Or it fails to boot?

The output of the command sudo fdisk -l (lower case L) might help to determine if you have wiped Windows or not.

Command above in bold red. Your output (the rest of the above) will more than likely differ; but you should see one or more partitions with 'HPFS/NTFS/exFAT' at the end (like the first two in my example).

M$ insist on a particular implementation of UEFI which effectively makes dual boot impossible.
GPT disk - secure boot & windows 8 with everything signed by m$
MBR disk & secure boot off - linux will boot

Suggest you forget windows 8. It's so horrible!

On the contrary, I have a Dell Inspiron 15R happily dual-booting Windows 8 and Arch. I just disabled Secure Boot in the BIOS (not an option for everyone, but it works fine on this laptop).

Though I agree, Windows 8 isn't great - though I'll probably warm to it in time (everyone's always very critical of new Windows releases while they get accustomed to it) it seems they've thrown out a lot of the genuinely good features of Windows 7 in favour of a new, seemingly broken UI.

@Snark1994: I'd be very interested in a step by step on how you succeeded, where many others have made a worthy attempt and failed. If the Dell Inspiron truly does dual boot with windows 8, I'm sure m$ will have them fix it after the next BIOS release!

I disabled Secure Boot in the BIOS, then essentially followed You need to boot in UEFI mode to do it, which for me meant following
