Hello everyone. Thanks for any help anyone can provide in advance. I recently thought i had a hard drive crash, but was able to transfer my windows 7 OS to another HDD. I saved it, but i didn't realize I had a virus and some malware on the newly transfered OS. I managed to fix it and windows 7 is now running fine. Before i fixed the viruses and malware ,however , I decided to buy a new hard drive and install a linux distro...I unplugged the windows 7 HDD and plugged in the new one just to be safe. I installed linux mint 13 mate with codecs using a live dvd burn by forcing BIOS to boot from the DVD drive. The two operating systems are running fine. Is it ok to plug both hard drives into the motherboard ? I had tried to plug them both in together before and it always wanted to boot into linux.(at the time i was running linux ubuntu 11.04) So how do i go about plugging both in @ the same time ? After i do get them both plugged in I need to set up EasyBCD to give me an option to boot whatever OS I choose or a timer with both os's in a chain startup...maybe a 20 second delay then boot to other OS. My main concern is plugging both HDD in with OS's on both already set up and running with user accounts.
