View Full Version : question about dual-boot windows 8 release preview

Hi all,

I have a question about dual-boot windows 8 release preview.

I have a Samsung Slate and would like to keep Win7 Pro on the SSD but to try out Win8 booting from a 32gb MicroSD. Is this possible? For a muggle?

I would also go for a dual boot single drive solution but I'm having trouble partitioning the SSD - I can only shrink the volume to about 1.5G and need 20. I can't figure out what I'm doing wrong...

No Windows 8 Release Preview can only be installed on an attached hard drive/solid state drive. External media (USB drive, MicroSD cards, etc.) cannot be used for an installation of Windows 8 Release Preview.

You can use these devices to burn the ISO File to instead of a DVD for installation media, but not to install the actual OS onto.

What app are you using to shrink the main partition down. The Win 7 Disk Manager should easily be able to do this. If you are having problems perhaps you can try a 3rd party App such as Partition Wizard Free home edition mini tool (http://www.partitionwizard.com/download.html), or the free EaseUS partition Magic (http://www.partition-tool.com/download.htm). I have used Partition Wizard very successfully.

Jackie, welcome to the Forum. Like Ted stated, Partition Wizard Mini Tool Home Edition is great at resizing HDD's, & has a plus for SSD's with their latest edition, partition alignment. This is essential for best performance & long SSD life. We'll discuss this in detail later, once we know what can be done. Just give me time to respond, I check responses often as possible (2-3 times per day).

First, how large is your SSD? Windows 7 will need more space than Win 8 RP does, around 64GB for Win 7 SP1 (& it's apps), Win 8 RP can get by with 40 to 45GB (for now). Once it becomes Retail, it may need more space, around 50 to 55GB.

These SSD allocations are assuming a minimum of apps installed, as you probably know, Win 7 can grow fast, very fast. But Win 8 RP seems to use far less drive space than 7 & Vista does. Thing is though, you need to have ample free space for SSD management features that Win 7 (& I assume 8) offers. Like TRIM & Garbage Collection. That SSD must remain below 75% Free Space for these functions to work. Don't depend on the manufacturer's specs to assume free space (like a 128GB SSD is actually 119GB) for you. In other words, don't assume that extra 9GB of space is really there when figuring free space.

I hope that you have at least a 128GB SSD on that Samsung Slate, as it's going to take that, as well as probable removal of your recovery partition, to make it work. If not, the good thing is, prices for SSD's are rapidly declining. Newegg often has 128GB SSD's for $80 to $90, on promo.

Please post back with your SSD specs & we'll see what can be done. I'll help you with the partition alignment as well. Really, you need to check it, whether or not you install Win 8 RP. It's essential for the long life of the SSD.
