Hi People,

Can I use my laptop (Toshiba R830) with eSATA port to boot my newly purchased SSD drive loaded with Windows 8.1 ?

I need to keep the existing internal laptop HDD with the OS untouched while loading the SSD drive on the eSATA casing with Windows 8.1 so I can install nested hypervisor for my test lab.

I don't have that model Toshiba laptop, but virtually all laptops (including my Toshiba) allow you to enter the BIOS and set the boot order for devices. So go into your BIOS (F2 on the R830) and reorder the boot devices to put eSATA above the HDD. Regards, Joe

Yes, put the SSD (with an OS on it) into an eSATA enclosure and place eSATA above HDD in the BIOS boot order (be sure to do a Save in the BIOS after making the change) and then it will boot from the SSD in the eSATA enclosure.

Thanks joe, is this applicable to the USB 3 case as well ?

I can't find eSATA had casing in the store bit there is USB3 casing, would that works better in terms of speed ?

Well, there's lot of discussion about eSATA vs. USB3 performance/speed. If you do a web search for "esata usb3", you'll get plenty of hits, including this PCMag article:,2817,2413310,00.asp

In your particular case, there are two points to consider: (1) How fast is your eSATA port – 1.5Gbps, 3.0Gbps, 6.0Gbps? (2) Does your R830 have USB3 ports and, if so, does it allow you to boot from them?

Here's an enclosure that supports SSD (and HDD) drives with both eSATA and USB3 connectors:®-eSATA-Enclosure-2-5-Inch-12-5mm/dp/B005B5G4S6/

I haven't tried this enclosure, but the overall customer review statistics are very good – a 4.3 average, but, as usual, there are some 1-star (the lowest) ratings, although there are 10 times as many 5-star (the best) ratings. I'd be willing to give this one a try, but it's your call, of course, and I can't vouch for this enclosure personally. Regards, Joe

By default the complete memory dump option is disabled in windows . If we want to enable the complete memory dump for a diagnostic purpose, we have a solution for it. here we are using the registry method to enable this.
