I ran into some interesting issues though, for one by default the Samsung Series 7 Chronos will not boot from USB devices, it wont’ list them as boot devices and you can’t see them without making a BIOS change. You go into your Series 7 Chronos Bios under Advanced and make sure Fast BIOS Mode is Disabled, this is critical, if your Fast BIOS Mode is Enabled, then the Samsung Series 7 Chronos will immediately try to boot from HDD or CD and won’t ever even scan or detect USB devices to boot from.
So that was the first hurtle I had to overcome, the 2nd was the Samsung Series 7 Chronos has 8GB Express Cache, which is like a soldered SSD drive onto the motherboard used to speed up access to common files. The problem is the ExpressCache shows up as Disk 0 in the partition wizard of Windows 7 and later. You do have to delete/wipe out the cache and not format it, it isn’t needed when running an SSHD or SSD anyway but I was still not able to get Windows 7 to ever install onto the Seagate SSHD drive.
The reason had to do with UEFI and AHCI to some extent, but all settings didn’t work. Windows 7 seems to refuse to be a boot drive when the HDD is Disk 1, and I found this out because I installed Ubuntu 14.04 without issue from USB stick to the same SSHD and it worked fine, I tried various tricks including Dual Boot, I tried Grub, Grub 2 and nothing I could do could trick the machine into booting Windows 7 from the Disk 1, even though I was able to get Windows 7 to fully install to the Seagate SSHD and be recognized by the USB stick as a valid and healthy install, it would never boot. The Samsung Series 7 Chronos would either keep rebooting over and over as it would only look to the Express Cache Disk 0 for an OS when only Windows 7 was installed on Disk 1.
In the end I just installed a fresh copy of Windows 10 and had no issues, I installed it via USB stick and had no problems whatsoever, the moment it installed the Samsung Series 7 Chronos had no problems booting to Windows 10 with it being the Disk 1 and the ExpressCache complication issue was immediately resolved. I think Windows 8.1 wouldn’t have had an issue either and it was a particular limitation with trying to re-install Windows 7 onto a new hard drive or SSD in the Samsung Series 7 Chronos. I was out $119 for the Windows 10 License Key but better than having to buy a new laptop.
Note, I am not a fan of the Samsung Laptops as a result of dealing with their BIOS, my other son has an ASUS ROG and it is fantastic, highly recommended.
