Episode 1306

Tony from Woodland Hills, CA
Windows 10 Start Menu

Tony has a Windows 7 laptop and he wants to replace the hard drive with an SSD and then dual boot with Windows 10. Leo says it's completely doable. Leo recommends backing up his data and then replacing the drive. Then he can do a clean install of Windows 7, and then do the Windows 10 upgrade. Then he can also choose a dual boot option.

There are a few pitfalls doing this, though. Leo recommends Googling "Windows 10 dual boot" for tips.

Why do I get an error message when I turn on my computer?

Gloria from North Hollywood, CA

Episode 1305

Gloria's Acer Windows 7 computer has an error code which pops up when she turns it on. Leo says that is a known error with Acer computers that points to an issue with the BIOS. The BIOS is a chip with a small program in it that runs immediately after turning it on. If there's an error message, it sounds like it could be corrupted or damaged. It could also be causing Gloria's inability to install Windows 10.

Why can't Windows play my videos?

Ron from Arcadia, CA

Episode 1304

Ron has Windows Media Player and he has videos taking from an old pocket camcorder. Now Windows Media Player won't play the videos anymore. Leo says that Ron is probably in "codec hell," meaning that the avi file needs a codec that Windows doesn't have it. The Camera probably uses a strange codec that Windows 10 probably deleted along with Windows Media Player. And even though you restored it, the codecs are all gone. Leo recommends trying to play it with VideoLanClient instead.

Why is Windows 10 stretched on my computer?

Alan from West LA, CA

Episode 1304

Alan has an old Dell computer and he is having trouble using Windows 10 because of the video problems. Leo says that Windows should be able to automatically read the native resolution and adjust accordingly. For some reason, Windows thinks the aspect ratio is wrong and it's stretching it to widescreen. It could be a driver issue. It may also be the text file that describes the attributes of the monitor. It's called a monitor driver.

Can I install both Windows 7 and Windows 10?

Glen from Winnetka, CA

Episode 1304

Glen wants to dual boot with Windows 7 and 10. Leo says it can be done. He can do the download and it should ask him if he wants to install Windows side by side. Will he be able to update both? Leo says absolutely. It'll be free, too, since the license is associated with the hardware and not the user. He'll have to update within the version he's using, though.

Glen should create his partition first. Then go into the Windows installer and choose the dual boot side by side option.

Why can't I upgrade Windows 8?

Brenda from Fort Paine, AL

Episode 1302

Brenda needs to upgrade from Windows 8 to 8.1. Leo says she definitely needs to do that. She says that Windows wants to uninstall Sentinel runtime drivers before installing, but she can't remove them because she hasn't installed them. Leo says it could be due to a program that she used in the past, or it was preloaded in her machine. It's probably from a trial antivirus. She's going to have to reinstall the trialware, and then uninstall it using their removal tool.

Why does my laptop reboot before loading Windows?

Matthew from Vienna, AUS

Episode 1301

Matthew has to reboot his laptop several times before it finally boots up. Leo says this has been an ongoing problem with PCs for decades and Leo believes it's a hardware issue in the overall PC design. He thinks it's because the laptop is cold and when it boots up, it takes awhile to get the connections warmed up in order to work. Leo says one way to test this is to reboot with a Linux CD and see if it boots up OK. If it does, then it's a Windows software issue, and reinstalling Windows should solve it. If not, it's a hardware issue.

Should I upgrade to Windows 10 from Windows XP?

Episode 1299

Chris from Lakewood, CA
Windows 10 Start Menu

Chris is still using Windows XP, but his computer is slowing down and his internet connection isn't that great. Time Warner says that if he upgrades to Windows 10, it'll give him faster internet performance. Is that true? Leo says it's true that the older a computer gets, the slower it becomes. He calls it "kruft." Leo backs up his data, reformats the drive and reinstalls Windows once a year. Chris can do that and upgrade to Windows 10, sure, but Leo advises going to Windows 7 if he can. If he gets a new computer, he will get it with Windows 10.
