I have a Gateway FX p7805u Laptop. It has a SATA HDD with windows 7 on it. I bought a SSD so that I can install windows 8 on it. What I did was remove the HDD, put in the SSD, and then installed windows 8 on the SSD. After the windows 8 install completed I put both the SSD and HDD in at the same time. These are both installed on internal sata ports. The problem is, that one of them is always put on the excluded from boot order list, and I cannot get it off. The one that is excluded depends on this following factor. If I remove both drives and then install one of the drives, let's say the SSD with windows 8 on it, and turn on my laptop, it will boot windows 8 just fine. If I then shut down, and plug in the HDD with windows 7 into the other internal sata port, when booting it will boot windows 8 just fine, but if I go to the boot menu, the HDD with windows 7 is in the excluded from boot order menu, and I cannot remove it from here. Now, if I remove both drives again. Place the HDD with windows 7 in, then my laptop will boot windows 7 just fine. Now if I shut down, and now place the SSD with windows 8 in the other sata port, the computer will still boot windows 7 and the SSD with windows 8 will now be placed into the excluded from booot order, and I cannot remove it.
I have the lateset BIOS and Chipset firmware, if it matters.
I have googled, and didn't even find one instance of something like this happening.
What is the windows boot loader though? Since one of the hard drives is always on the exclude from boot order list, windows never pops up with a choice as to which operating system I want to boot from. This is what I have read that other people see...but i think that has to do with when both operating systems are installed on the SAME drive but with partition....I dunno I may be wrong....but either way I dont know if that is the "windows boot loader" you are talking about, or something entierly different.
