Since my original copies of Win 7 do not have SP1 included, I downloaded a genuine (legal) ISO of Win 7 Home 64bit with the service pack already included. These legal ISO's are available at Digital River if you are interested.
I burned the ISO in my Samsung SH-S203B on a TY 8x +R disc. No issues to report, and I took it out and labeled it with a Sharpie. But when I rebooted to test it as a boot disc, the computer completely ignored it in the Samsung drive. Zilch, zip, nada.
I put it in my second drive, an LG GGW-H20L, rebooted and it recognized the disc as bootable and fired up into the loading sequence for the operating system.
So what gives? The Sammie is recognized in the bios and in the operating system. No warning signs posted for it. The Samsung burns properly and plays both dvds and cds with no issues. Just won't boot from a bootable disc. I tried another bootable disc just to be sure, and it didn't work either.
This computer has two SATA controllers. One is the AMD SB850, with six 6gb SATA ports and the other is the Gigabyte (JMicron) with two 3gb ports. The AMD SB850 is set to AHCI, the Gigabyte is set to IDE mode. I have both of the optical drives connected to the Gigabyte controller.
Since the LG is working properly, this isn't a major problem, but I can't figure out what is going on with the Samsung.
