dual booting from 2 HDDs

[suri2001]

Dear community,

 

What ive learned so far is: the way to enlightenment is a stony path.

 

what worked is:

insatlling myz cd on external hd usb/or fw or internally

 

what didnt:

dvd player MUST be on 1st bus

 

however, ive found many howtos dual booting from 2 partitions, but none with two drives.

 

after successfully installing os x, i cant choose my win hd in the osx bootloader, it always boots os x

 

and trying to solve it with an exterbnal osx hd and the bios via boot prority doesnt work either, it doesnt recognize the ext drive neither connected as fw or usb

 

what a i doing wrong, please help!!

 

thx in advance...
