If you like to run your favorite Linux distribution alongside a copy of Windows on the same machine then you might want to stay away from Windows 8 computers. Thanks to a new secure boot in Windows 8, dual-booting might just become a thing of the past.

Now before I begin explaining, let me say that this will affect only those devices with a Designed for Windows 8 logo on them, so you can still install Windows 8 on your current computer and dual-boot it. The reason it woill not work on these branded computers is because of the UEFI or Unified Extensible Firmware Interface that these machines will be having instead of a traditional BIOS.

The UEFI requires a signing key installed on the firmware from the software maker or the OEM before booting into the OS. This makes it harder for malware to initiate when the system is booting. Unfortunately, this also means that an unsigned copy of Linux will not be able to run on a machine with such a firmware.

There are multiple listings for the Samsung Windows 8 tablet and some auctions are reaching over $3,500. Of course, you can download the software right now from Microsoft developer website but the hardware itself is pretty nice, even if it comes with a fan: 11.6-inch screen, Intel second-gen i5 processor, 64 GB storage, 4 GB of RAM.

These Windows 8 tablets are available on ebay right now for different prices.

Windows 8 could support voice calls, its been suggested, after a Metro UI tile for phone functionality was spotted during a BUILD 2011 session last week. The slide, istartedsomething caught, has a Windows Phone 7 style "Missed Calls" dialog complete with times and dates of recent incoming voice calls. However, its also possible that this could be a VoIP service, or indeed some form of wireless call management when pairing a Windows 8 tablet or phone with a Windows Phone 7 handset.

The information comes from the screenshot above, which features a missed calls pane in its Metro UI. And that could be used for some VoIP services, so you should not get all too enthusiastic about it just yet.

We have been itching to get our hands on Windows 8 which is still just a working title, by the way ever since the first screenshots surfaced. But when Microsoft officially unveiled it to the public yesterday the itch turned into a proverbial rash.

Now we have three different files here to download. The first is the full blown 64-bit version that comes with the OS as well as developer tools. If you are a developer wanting to get a feel of the Windows 8 SDK then this is the version to download. You will have to perform a clean install with this version.

The second version is 64-bit just like the first version but comes sans the developer tools. You can retain your accounts files and settings if you choose by opting for this version.

The third version is identical to the second one but is 32-bit.

In each case the download is an ISO file that you will have to burn on a disc or a bootable thumb drive. You will need a dual-layer DVD for the developer version, as well as a drive that supports burning and reading them. System requirements for running Windows 8 Developer Preview on your PC are as follows:

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
• DirectX 9 graphics device with WDDM 1.0 or higher driver
• Multi-touch display for using the touch-based functions

Do remember this is a beta software. There can and will be bugs and certain apps may not work correctly. Issues are part of testing a beta software and as usual, should you choose to download a beta software you instantly lose the right to complain about the bugs and issues that you may face while using it. DO NOT install it on your primary computer, especially if it is your work PC.

Microsoft just unveiled some more details about its ambitious Windows 8 operating system at Build 2011 and we have been playing with a prototype tablet for almost 24 hours and we must say that there is a lot of promise with Microsoft new platform.

Windows 8 is not the company tablet-specific OS, as it is the next generation of its platform and its meant for screen sizes from 7 inches to 70 inches. Of course, the success of devices like the Apple iPad are definitely a factor in this, as the whole thing has been rethought with responsive multitouch in mind and a big focus on apps.

As for the Samsung tablet, its not quite what was rumored; but its still quite a powerful machine with an 11.6-inch screen with an 1366 x 768 resolution, a second-generation Intel core i5 processor, integrated 3G from AT&T, 64 GB of on-board storage, 4 GB DDR3, multiple dock sensore and two cameras. Microsoft specifically said this should not be considered an iPad killer, as the device is meant to be a developer preview machine and when it finally lands in the market, it will run Windows 7.

The point of the tablet is to show off Windows 8 and its multitouch capabilities and its worth crowing about. Once you boot it up, you Windows Phone 7 fans will recognize many elements: from the live tiles on the start screen to the loading animations and even the sounds and look of the virtual keyboard, Windows 8 builds upon the visual aesthetic of Microsoft latest smartphone platform.
