How I Fixed: “Windows cannot be installed to this disk…..”

Windows cannot be installed...

Hello everyone,

A client gave me a Dell 660s Windows 8.1 desktop that would not boot. It was stuck in an automatic repair loop, but nothing was being repaired.
Just for good measure, I installed a new SATA hard drive and I was set to reinstall the 8.1 operating system. Piece of cake right?
Not quite. Every time that I attempted to clean install Windows 8 these messages appeared:

Windows cannot be installed to this disk.
This computers hardware may not support booting to this disk.
Ensure that the disk’s controller is enabled in the computers BIOS menu.

Here is how I solved the problem:

1) I went into the Dell BIOS (at the Dell logo during restart, tap the <F2> key repeatedly).

2) I disabled UEFI Secure Boot

3) I disabled Fast Startup

4) I changed the Boot Mode from UEFI to Legacy

5) And finally the clincher (in my case): I changed the SATA mode from AHCI to ATA

I booted the machine back up with the Windows 8 installation disk in the CD/DVD drive and the Windows 8 operating system installed as it should. Success!

Best wishes,
Randy The Tech Professor

Third Party Program Updates For The Month Of February 2015

It’s just not enough to keep your Operating System patched. Many malicious exploits are finding entrance into your machine through third party programs. Below are the February 2015 third party patches. I recommend removing local admin rights on your computer (#4 here) to lower the risk of being bit by software like Adobe, Chrome, and Firefox. Get updated/patched as soon as possible!

Not Getting 50 Mbps Download Speed From Comcast? Here’s How! (Part 2)

Comcast Xfinity Speeds

Hello everyone,

I have received many comments from my first Comcast post back in March of 2012. Many people in my area, and around the country are using Comcast and there are many questions about both wired and wireless Internet speeds. Here are my latest suggestions:

1) Comcast has increased their Internet speeds: “Performance” now offers speeds up to 50 Mpbs (up from 25 Mbps), “Blast” is now 105 Mbps, (up from 50 Mbps), and “Extreme 105” has been bumped to 150 Mbps. I have not seen the 150 Mbps offer in my area of Tennessee.

2) Comcast has come out with new Docsis 3.0 modem/routers in order to handle their speed increases. The two that I am seeing in my area of service are the Wireless Gateway 1 and the Wireless Gateway 2. You can rent these modem/routers from Comcast or buy them. I would buy them if I were you.

3) These new modem/routers are very decent. They have four 10/100/1000  Gigabit Ethernet Ports and they will definitely get you the speeds (wired) that Comcast advertises.

4) The wireless capability of the router is not bad (the Wireless Gateway 2 is dual band). If you want more speed/distance, call Comcast toll free (855-308-9452), and have them put the Gateway into “Bridge Mode”. Then you can use your router of choice (make sure that it is a 10/100/1000 port/switch router). I like this one. Even though 802.11ac speeds are higher than 802.11n, I don’t think that they are high enough to justify the higher price.

5) Once the Comcast technician has put the router/modem into bridge mode, ethernet ports 2, 3, and 4 will no longer work (disabled). Connect a Cat6e cable from port 1 of the Comcast Gateway to the WAN port (Uplink/Internet) of your router of choice. Now you can configure your router as you like.

6) Wireless speed will vary (router positioning, house construction and layout, etc.), but it will be very good. If you are paying for the 105 Mbps tier your wireless speeds will of course be faster than that of the 50 Mbps tier.

Please feel free to comment. Let me know about your Comcast Internet experience.

Best wishes,

Randy The Tech Professor
