Grub is not showing Windows 7 when booting my laptop

[Daniel - Asterisk]

Hello all,

 

I'm completely novice with grub and I have a problem, I was re-installing ArchLinux (/dev/sda2) in my laptop with existing Windows 7 (/dev/sda1), but after re-installing grub and running following commands I lost Windows at boot time. I think Windows is still there and I want to recover it.

• grub-install --target=i386-pc --recheck=/dev/sda
• grub-mkconfig -o /boot/grub/grub.cfg
• exit
• poweroff

 

Thank you!
