If a UEFI Firmware Settings option appears, select it. On the Choose an option screen, click Troubleshoot and then click Advanced options.
(Despite the terminology, your PC will not immediately restart! This is normal.) Click Recovery and then, under Advanced startup, click Restart now. On the PC settings page, select Update and recovery. Open the Charms bar, click the gear icon (Settings), and then click Change PC settings at the bottom of the bar. The following explains how:īIOS/UEFI access for Win8.1 PCs (Win8.0 is similar): You will probably need to remove the feature from UEFI/BIOS. Most Windows 8 PCs utilize UEFI and Secure Boot, to prevent thieves from booting your PC from another disk, such as a Linux disc, to get at your hard drive contents. Could I just boot from a Win8 installation CD without any problems or are there things I have to bypass? I was wondering if this applied to my specific laptop, or if it also applied to reformatting with a new version of Windows 8. I heard a lot of rumors about it being purposely hard to down-grade (or up-grade, some would say) to Windows 7 from Windows 8 because there are some prevention mechanisms built in to the laptop (maybe not this one specifically, but Win8 laptops in general). It came with a lot of bloat from Toshiba, so I got an OEM Windows 8.1 disk ready so I can reformat it. The only course of action I can think of is reformatting.Īnyways, the computer is a Toshiba Satellite P55-A5312.
There is something wrong with my Windows installation because before I even installed anything the day I first started using it, everything on the OS level has been horribly laggy. I've ran benchmarks for every component, and they work as they should. Just by looking at the few components, you can tell this computer shouldn't be slow. The computer itself has an i5 (mobile, of course) and 6GB ram. I know it's the OS and not the hardware because programs work fine, but when navigating through the Windows programs (regedit msconfig basic menus and folders), they get slow and have about a 5 second click/type lag. I need to reformat a laptop I got that has been experiencing extreme lag since day 1.
