grub error after install Arch x86_64

i install arch on my second laptop and everything works fine so im install on my main laptop but grub can boot

my main laptop have 2 HDD, first i have windows seven and other partions on second i have arch64
at install no errors are show but when i reboot grub menu show the arch options i choose and

Booting command-list

root (hd1,0)
     Filesystem type unknown, partition type 0x7
kernel /boot/vmlinuz26 root=/dev/sdb1 ro

Error 17: Cannot mount selected partition

Press any key to continue... 

the hd1,0 thing is correct is the second HDD, first partition
i only can boot by arch live cd choose boot  existing OS edit to hd1,0 and show me the grub menu and all boot option work

so what the problem with that

is not the problem with windows because i dont put windows on grub if i wont boot windows i choose boot first HDD on bios

the previous distro in this machine was sidux and only works on install i just choose install grub on sdb on MBR
on arch i choose install grub on /dev/sdb i think this is the MBR correct?

Re: grub error after install Arch x86_64

your second hard disk, become _first_ hard disk when you change bios secuence. So it is hd0, not hd1 _only_ for grub.

0x7 (NTFS) is your win partition on your real first hard disk.

edit: aclaration: this is only for grub, contunue with /dev/sdbX for Linux

Re: grub error after install Arch x86_64

You can easily load Windows from grub as well. Windows usually wants to be the first disk in order to load though. You can fix this by adding these lines in the windows menu item:

map (hd0) (hd1)
map (hd1) (hd0)

It will remap the drive order before loading windows.

Re: grub error after install Arch x86_64

this i find on archwiki, i have this on grub too, but the problem is the grub/bios wrong names but is 100% now.
on 1 HD is a peace of cake install arch on 2 HDD im install a few times because this error but is easy too, when i read on web arch is hard to install i think that will be a pain in the as* but not really is easy and fast even faster than sidux but on start up have more 100mb of ram than sidux but is not a problem because is faster lol

thanks
