Once a week we round up some of the reader letters we’ve answered and share the advice with everyone. This week we’re looking at how to search within web sites, downloading apps from places other than Google Play, and getting started with dual booting operating systems.

How Can I Find an Article I Forgot to Bookmark?

Dear Home Theater,

I saw an article on HTG a few months ago that covered how to build your own high-gain projector screen. I didn’t bookmark it and now I’m having trouble finding it? Would mind sharing the link with me? Thanks!

Sincerely,

Home Theater Builder

The easiest way to find an article on HTG, or any other website you’d like to search within, is to use a little search hack in your Google search query. By searching for “site:sitename.com your search terms” you can restrict your search to just that web site. To find the link for you, we simply plugged in “site:howtogeek.com beads projector” and the article you were looking for was the first result.

The site: trick is a great way to find articles and information when you know you saw it on a specific web site but you don’t want to go digging through that site’s archives to find it!

Where Can I Go for Android Apps Beside Google Play?

Dear Techno-Grump,

Maybe I’m being an old techo-grump, but I’m not particularly enamored with the new Google Play (previously Android Market). Is there another venue to check out Android Apps? I know I’ll still end up at Play for a lot of things, but I’m interested in looking at other places I can grab apps.

Sincerely,

Techo-Grump

What Do I Need to Know to Get Started with Dual Booting?

Dear Dual Boot,

I’ve never dual booted before, but I think it would be fun/educational to start doing it. I’m currently running Windows 7 and would like to dual boot to other operating systems so I can try them out without giving up the OS I’m comfortable with. I have no idea where to start?

Sincerely,

Dual Boot Dreaming

Although dual booting seems foreign to you now, we assure you with a little reading and playing around you’ll wonder why you didn’t start sooner. We’d highly suggest checking out this roundup of our best dual-boot articles including How to Dual Boot Windows 7 and 8 Without Re-Partitioning (Using VHD). You’ll also find tips on dual-booting Windows and Linux.
