UEFI / Secureboot Preventing Linux Bootup - Will Windows 8.1 Work After Removing It
Apr 30, 2014
Okay now I have an issue with windows, namely secureboot and UEFI. HP Pavilion laptop that came preinstalled with windows 8.1 but didnt like it and wanted a dual boot.
So I gave him Ubuntu 13.10 as it has UEFI support and everything was fine until we updated to Ubuntu 14.04. Sadly it did not load windows via grub and windows would fail to boot.
However after repairing the windows boot manager I knew I had to reinstall linux which would normally be fine but now windows and windows alone now boots, no grub, no nothing.
I heard recently of this story: [URL] ....
However I checked everything and windows seems to be the cause of my woes. As does UEFI. Now we would like to keep windows on this machine however I am thinking of removing the /efi partition
Will windows 8 still work if I do this?

I recently installed windows 8 using the "windlows 8 upgrade assistant", install went fine. got into windows 8, but it never replaced my MBR, which currently holds an installation of a linux bootloader known as "grub".
All guides point to having an installation dvd. to boot repair, then repair the mbr with a command in command line
I need another solution, since ive installed using the upgrade assistant, i dont have a dvd.

I recently felt the urge to experiment with Linux and installed Ubuntu Mint and tried to set up dual booting.
However I seem to have only suceeded in preventing Windows booting at all. I cannot get into the recovery drive to undo my wrong doing.
How can I reset the windows boot manager without access to windows or recovery partitions?

Today, I installed Linux Mint 13 to try some appliactions, programs and other good things.I downloaded it normally and after installing it I don't have network connection.
I tried with all type of network switches and activated Legacy Network Adapter but it don't work (I configured in network adapter for ex. External Network 1 , I want to say it's not say : Not Connected in VM Settings).
When I turn it Linux Mint says : Disconnected - you are now offline.
How to configure network and the Internet to work with Linux Mint VM ?

Past Friday windows 8.1 ran some updates and I think it's since then the watermark with SecureBoot disappeared from my desktop.
I tried to remove this watermark before with my friend; My2cents. But we couldn't remove it because I had not eufi boot control panel. He told me he would provide a workaround to remove the thing and now it's solved.

It's not just your everyday slowness. I accidentally dropped my computer, not too violently or anything, and now it's having extreme lag.
Even before you boot, it takes about 3 minutes just to wait for the safemode options screen after hitting F8. So far, it's taken 20 to actually load the files and start safemode.
The only thing I can think would be causing this is the RAM cards were damaged? Or it might also be a softwear issue - I was running a high memory video game when it fell and shut off.
I have a Samsung 64 bit Notebook with Windows 7 Home Premium.

I'm just messing around with some configurations, at the moment with the aim of increasing productivity on my Win 8 laptop. I just scheduled a shutdown task, to be run every night and in the process I was wondering if there's anyway to prevent either:
Your computer from starting before a certain time or the operating system from logging you in before a certain time.
As an example, say I wanted to limit access to my computer before 9am how could you go about this?

When I shut down my computer, I get this thing that a program is preventing shutdown. It doesn't tell what's the name of the program, it only says that "This program is preventing shutdown".
Can any hacker see my webcam or my pictures without putting any malware or virus to my computer and without me doing anything so they can see me?
My computer is HP Pavilion 15 with Windows 8.1.

I'm always using a mouse... so I keep my touchpad disabled with the hotkeys so I can type and work without the risk of pressing touchpad.
But each time I logon, or bring my pc back from sleep, windows turns my touchpad back on... this is really frustrating.
Is there a way to prevent windows 8 to turn my touchpad on each time I login? My notebook is a lenovo b590.

I just bought this Dell XPS 8500 with Win 8 on it and although I'm not that happy with this OS I guess there is a learning curve so I'll try for awhile.
For some reason, after I had uninstalled Mcafee from the start up screen and also added a few items to the startup screen, when I reboot or do a cold boot, instead of getting the startup screen, I am getting the desktop along with about 5 disk partitions and a couple programs that I installed. While this is not bad since I can just "x" out of them, it's irritating and wonder how I can fix this. I would like to ultimately just boot up to the desktop if possible without anything else opening up.

I have recently set up a Win 8.1 notebook and from a cold boot Win comes up with a confusion by showing part of my email address as user (a hangover from a MS account) but, after saying that the username is incorrect, then allows me to enter my local account / network creds.
I decided that, since the machine could go on the road from time to time, I would reintroduce the need for username and password. I would like to tidy up this mixed-up situation by having to enter my local account details and not have this 'error' message from dear old MS pop up. Having part of my email address appear on bootup is hardly useful in terms of security.

I just had a BSOD for the first time, it occurred during a shutdown. A program was preventing the shutdown, but I couldn't tell what it was (was trying to go to sleep). It occurred after encountering some weird problems. First after playing Mass Effect 3, my Ethernet port was somehow disabled, and I couldn't connect to the internet. Then I decided to play some insurgency, then insurgency crashed. I had to close it via task manager along with steam. After that I decide to shutdown my computer, it was taking long, and then it BSOD.
Afterwards I ran a sfc scan, and it came up saying something like it found some corrupt files but couldn't fix them all
I fixed the ethernet port problem, by re-enabling it (I was still able to connect to the internet via WiFi). Also ran a virus scan with Mcafee nothing showed up.

I've noticed that even though I didn't run 'Reader' it's running and in Task Manager. At times I also see 'Store' running when I haven't run it. Any way to prevent unwanted apps from running?? I'm well aware of how to close them.

I didnt have this problem in windows 7 and it makes me want to go back to it sometimes because if this glitch.
windows 8 boots and after logging in,sometimes doesnt start programs that are set to load.
EFI installed with GPT
intel 2600
16gb memory
nvidia 580gtx
2tb drive
I have fastboot disabled
programs that sometimes dont load
msi afterburner
logitech mouse software (without the software my g5 mouse is slow)

rebooting the computer fixes the problem and all programs load.
This problem also happens on a fresh install after a couple of week and the event log is field with errors stating the service could of start, failed start, couldnt find service.
I ran chkdsk,sfc and all passed. And like I said rebooting the computer loads fine and event log for the reboot shows no errors.

Just today, my desktop's been unable to boot into the login screen on Windows 8.1 due to a blue screen that appears for a split second, and forced the PC to restart. Some of this, I think, should be surely linked to the GPU, as it's left me with a black screen and loud fan noise about three of four times today. Each time I've restarted the PC, it's been able to to get back into Windows, though this time it's just giving me a BSOD that I can barely see at all.
What I'm wanting to know is how can I get it to show me the information for me to diagnose it. Could I use a shortcut on the keyboard, or will the information be saved somewhere?
The GPU I have is the XFX 7950 Core Edition.

I'm using the latest version of FF in Win 8 64-bit. I have the FF pop-up blocker enabled and also the ad-block extension. But I'm still getting these annoying pop-ups that slide in from the sides or top or bottom of the screen and hover, asking for opinions or ratings.

Just received this for Christmas and turned it on. It will show the Alienware logo and F8/F12 prompts. After that the screen goes blank. Start it up again, goes thru logo screen and then a blue screen pops up saying that your pc couldn't start. It comes up with different options like safe modes and disabling options. Choosing any of these options just shuts down the pc. Its an X51 running or attempting to run windows 8.

I just updated to 8.1 two days ago. I agreed to the update when my computer boot up, without issue, and was forced to reboot immediately (which, by the way, is idiotic. I wanted to do the install at night when I went to bed not lose my only computer for 1.5 hours that were suppose to be spent on volunteer activities because it won't let me delay the install!)
When my computer next booted up it was SLOW. I opened up task manager and it showed me at 100% disk IO, even though non of the programs running used enough disk IO individually to be anywhere close to the 100% mark. Even after all of my programs *finally* finished booting up the disk IO still showed at 100%, but every program on my task manage showed less then 0.3 MB/s and most were at 0.1. Eventually the diso IO goes back to a reasonable level, but I had enough time to search all over google and fail to find any answers before my IO went to 0 so it was hardly immediately. This is substantially slowing my bootup process.
I have checked all the bootup programs and they all look right. a *quick* scan of msconfig bootup (I already use a selective bootup from msconfig) looked right as well. I ran a malware scan and nothing came up. However, I didn't expect any of those to be the problem anyways. My computer was fin when it booted up without 8.1 I used it for 20 minutes visiting the same website I always do, then I was forced to do an install and everything was broken. This clearly sounds like it was caused by the 8.1 upgrade.
I will update with screen captures of task manager when I next reboot; My disk IO stayed at 100% so long I figured I could take the captures when I needed them, then it finally went to 0% the one time I actually wanted it to stay at 100% ...

I have Windows 8 installed on 2 Samsung SSDs - one is 840 Pro and the other is 840 Evo. This is because I work on both video and music production and would like to keep things separate.
At first I tried cloning an "old" SSD on to both Pro and Evo to make life easy, but it was a total mess:
I would boot Windows 8 on either Evo or Pro, and before the password prompt, Windows would fire up a Checkdisk on one (or more) of the 5 HD I have (please find the logs and disklayout in the attachments).
This would usually happen if for eg, I'm working on Evo and then I restart to work on Pro - or vice-versa.
But sometimes I would be working on either one of them, and this flag notification would popup asking me to restart because Windows needs to perform a diskcheck.
What is strange to me is that if I do a manual diskcheck (right-click -> Properties -> Tools), it would complete it, the notification disappears but would return a second or two later.
There was a minor issue where for eg, some options in the Control Panel were still pointing to drive H: which before the cloning, was my original C: drive.
Otherwise all software was working perfectly fine.
So I decided to do a clean re-install on both Pro and Evo hoping to solve this diskcheck issue once and for all.
This was 10 days ago, and for the past 10 days I had used almost exclusively the Evo drive. Today I need to work on Pro but Windows wouldn't get past the diskcheck and on to the password prompt.
It's saying "Preparing for Repair", then changes to "Diagnosing your PC" but then this blue screen pops up asking me to choose between Shut Down or Advanced Options.
This happened on rare occasions, but before the fresh install, I would do this perhaps a couple of times in a row (i.e. go to the blue screen Advanced Options and click Exit and Continue to Windows 8) restart, and it would eventually go past the diskcheck and allow me to log in and work. But today it just won't do it.
EDIT: I don't know if it matters but as it is now, it automatically boots up on Pro unless I hit F12 and choose to boot on Evo. But as I said earlier I had only been using Evo for the past 10 days since the re-install.
Attached please find the Srt logfiles which I found by following a path shown to me on that blue screen.
The strange thing is that the path started with drive H: and why drive H: and not C: (i.e. the Pro drive, being the current Windows boot drive). But when I booted on Evo, and went on drive J: (the drive letter that Pro is assigned when I'm on Evo), I found the logfiles there.

Ever since I've built this computer and installing the latest drivers, I've run into a problem where the computer BSODs with a "DRIVER_POWER_STATE_FAILURE" error, and it happens whenever it's been off or in sleep mode for a long time. I've tried looking up solutions and most say that a bad driver is the issue, but the device manager doesn't show me any problems.

My Intel HD 4600 graphics puts 3 little apps to be started automatically. I know they are related to: intercepting hotkeys - hkcmd.exedisplaying tray icon - igfxtray.exedisplaying settings GUI - igfxpers.exe The thing is that I don't use hotkeys and have disabled them in Intel Graphics options, I've also removed Intel Graphics icon from the tray.
Thus, I'd expect the first two Intel apps to be removed from items set to auto-start at system bootup. However, they are still there. Is it correct? Shouldn't they be disabled when related functions are turned off?
Is it safe to simply delete the related registry entries and leave only the last app?
