• Disable laptop's display on boot when used with external display

  - by Ryan

  I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.) The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising. Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?

• Winlogon Init delay

  - by iceman

  I am trying to trace the boot time of a Windows 7 Professional machine and found the following times: Phase #, Phase Name, Start Time (s), End Time (s), Duration (s) 1, Pre Session Init, 0.000000000, 6.218684586, 6.218684586 2, Session Init, 6.218684586, 19.716180585, 13.497495999 3, Winlogon Init, 19.716180585, 164.393575644, 144.677395059 4, Explorer Init, 34.856013361, 39.280802294, 4.424788933 5, Post Boot, 39.280802294, 85.280802294, 46.000000000 The winlogon init seems to take a long time. What can be a reason?

• Can't boot into Ubuntu from CD, or from Acronis True Image recovery disk

  - by ChrisA

  I can boot my computer off a home-burned-from-ISO-image Windows 7 (x64 or x86) installation CD, without problems. It's a Quad 6600, 4GB RAM, 8800GT and most of the time runs Win7 with no problems. However, if I boot off a CD containing Ubuntu (10.04 or 9.something IIRC), or a recovery disk created with Acronis True Image Home 2010, it: boots starts to load the OS from the CD then hangs ... and I have to reset. I've tried all these CDs on another computer, and they boot up into Ubuntu or Acronis respectively with no problems at all. Any ideas what to look for? Sorry this is a little vague but I have no idea where to start, really ... if there's more information needed I'll edit the question. TIA!

• HDD from Mid-2009 MacBook Pro works OUTSIDE laptop, but not INSIDE.

  - by Jaime

  Leading up to the problem: I was working late one night on a Keynote presentation. My battery ran out, and the computer did that hibernation thing it does when there's no battery power. I got my charger, connected it to my computer, and then pushed the power button. It started up for a second in to the gray screen it usually goes to. Then I turned around, tugging the magsafe charger out of the connector on the computer. This caused my computer to shut down again. Now I can't get it to boot at all -- just a blinking folder icon with a question mark in it on boot up. I've tried pretty much everything to deal with this. Multiple forced reboots, resetting PRAM and NVRAM, etc. I booted to original OSX disc and ran disc utility, but I discovered that there is no disc to boot to. I ran the Apple Hardware Test, and it came back 100% good. I booted to an Ubuntu live-boot disc and ran that disc utility, just to see if it recognized a disc at all. It didn't. So I removed the HDD, and replaced it with a bootable volume running BSD. It didn't recognize that HDD either. I then attached my HDD to my computer via an external enclosure with a USB interface. Lo and behold, it booted! So my computer now only work with my HDD attached externally. This means that the HDD is functional. And the AHT returns no hardware malfunctions. So what the hell is going on? … In the meantime: I've put the HDD back into the computer but it still doesn't do anything at all (I'm running it externally right now). I just checked the serial number and my 1 year warranty expired recently, so I can't send it back for repair. … Little Help Thoughts? I've been searching everywhere for leads, but no luck. …

• Couldn't dual boot Vista and Centos 5.4

  - by jack sparrow

  Hi all, Today I have installed Centos 5.4 with dual boot with Vista. Everything was fine, but after testing Centos 5.4, when I tried to load Vista, it did not load. After selecting vista from grub menu, it shows the following message: rootnoverify (hd0, 1) chainloader +1 No bootmgr found I googled and try to fix the boot but failed, Then I restart my machine, boot with vista cd and in rescue option, restore my bootmgr by typing bootrec /fixmbr What happened after that, I can load at vista now, but no grub menu shows :P It seems the Centos went totally invisible. I am using dual booting Ubuntu 9.10 and vista in my laptop and its working fine and with no error from the beginning. But installed Centos for one of my project needs and I need it running asap. So I am feeling very helpless. Please help me anyone out there. I know there are many people knows how to fix it. Please help me.. Thanks in advance.

• Hibernating and booting into another OS: will my filesystems be corrupted?

  - by Ryan Thompson

  Suppose I have Windows and Linux installed on the same computer. If I hibernate Windows, can I boot into Linux without corrupting the Windows filesystem when I resume Windows? What about the other way around? What if I hibernate one, boot into the other, and mount the hibernated filesystem read/write? Read-only? If this is unsafe, is there any way to detect the hibernated state of the other OS and prevent mounting its filesystem? Basically, how far can I push this before it breaks, and how dangerous is it near the edge? I think I know the answers to some of the above questions, but for other ones, I have no idea, and for obvious reasons I have not tested this on my own computer. If someone has tested these, please enlighten the rest of us. I'm not necessarily looking for a specific answer to every question; I'll accept any response that answers a reasonable portion. EDIT: Let me clarify that when I say "hibernate," I mean the process of writing the contents of RAM to the hard disk and completely powering down the computer. In this state, powering the computer back on brings you through the BIOS and bootloader again, and you could theoretically select another operating system on a multi-boot system. Anyway, on with the original question: RESULTS Ok, after everyone's assurances that this would work, I tested it for myself. I set up Ubuntu to remount all ntfs filesystems and external drives read-only before hibernating. There was no need for a similar Windows setup because Windows does not read Linux filesystems. Then, I tried alternately hibernating one operating system and resuming the other, back and forth a few times. I even tried mounting the Windows filesystem from Ubuntu read-write, and creating a few files. Windows didn't complain when I resumed. So, in conclusion, you can more or less freely hibernate in a dual-boot Windows/Linux scenario. Note that I did not test a dual Linux/Linux co-hibernation situation. If you have two or more Linux installs and you hibernate one of them, you might be able to corrupt the filesystem by mounting it from another.

• Ubuntu terminal only at startup

  - by officespace

  Hi, usually when I boot into Ubuntu 9.10 nowadays, I get a terminal only (no desktop, etc) asking me to login. Once I do, I still only have terminal access. It takes somewhere between 3 - 10 restarts to get it to boot up normally. If anyone has an idea of what's going on, I'd appreciate any help.

• Make GRUB automatically boot Ubuntu

  - by Matt Robertson

  I am running a dual-boot with Ubuntu (10.10) and Windows 7. Recently I edited my /boot/grub/grub.cfg file to only show one version of Ubuntu (as opposed to several kernel versions) and Windows, simply by commenting out all other menu entries. My question is if I can edit GRUB to just boot a specific entry automatically. I tried removing all other menu entries, but GRUB still showed the menu with only one entry. I've also considered just setting the timeout to either 0 or 1 second, as this would basically achieve the same thing. What is the best way to do this?

• Unable to boot Ubuntu 64-bit in Virtualbox on Mac OS X

  - by Aamir

  I have latest generation Macbook Pro 7.1 (Intel Core 2 Duo) running Mac OS X 10.6.6. I installed Virtuabox 4.0.2 and tried to boot Ubuntu 10.10 64-bit iso. The boot options screen from the live CD came up: However when I continued to load the live session, or installer for that matter, I encountered the following error: This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU. I am not sure if VT-x is enabled or is supported in the Core 2 Duo of my Macbook Pro. But at least, I have both I/O APIC and VT-x enabled for hardware virtualization as told in the Virtualbox manual.

• Ubuntu not booting, recovery mode not loading

  - by TNC

  I have a dual-boot Ubuntu 11.10 and Windows 7 machine setup and last night I had to force shutdown Ubuntu during updates because it wasn't responding. Since then, Ubuntu will not boot up, only flashing a blank lit screen for a split second every couple of seconds. Booting in recovery mode does not help either, as it doesn't load at all. If anyone can help me diagnose what's wrong and figure out what to do, that would be greatly appreciated!

• If USB is not listed in BIOS as a boot option, does that mean the machine can't boot from USB?

  - by Chace Fields

  I just purchased an Asus Zenbook Prime UX31A-DH51 with Windows 8. I want to wipe the drive and do a clean install but USB is not listed as a boot option in the BIOS. Does this mean it is not possible? Here is a photo of my BIOS options. This is the only option I get when I click Add New Boot Option. Not sure if I can add USB here. * Update * Asus tech emailed and said: "Unfortunately with Windows 8 you can not boot from bios."

• Backing up my data causes my server to crash using Symantec Backup Exec 12, or How I Came to Loathe Irony

  - by Kyle Noland

  I have a Dell PowerEdge 2850 running Windows Server 2003. It is the primary file server for one of my clients. I have another server also running Windows Server 2003 that acts as the core media server for Symantec Backup Exec 12. I recently upgraded from Backup Exec 11d to 12. This upgrade was necessary because we also just upgraded from Exchange 2003 to Exchange 2007. After the upgrade I had to push-install the new version 12 Backup Exec Remote Agents to each of the servers I am backing up (about 6 total). 5 of my servers are doing just fine, faithfully completing backups every night. My file server routinely crashes. Observations: When the server crashes, it does not blue screen, it just locks up completely. Even the mouse is unresponsive. If you leave the server locked up long enough, it will eventually reboot itself and hang on the Windows splash screen. There is absolutely zero useful Event Viewer evidence of a problem. The logs go from routine logging to an Unexplained Shutdown Event the next morning when I have to hard reset the server to get it to boot. 90% of the time the server does not boot cleanly, it hangs on the Windows splash screen. I don't have any light to shed here. When the server hangs all I can do is hard reset it and try again. Even after a successful boot and chkdsk /r operation, if you reboot the machine, you have a 90% chance it won't back up again cleanly. The back story: This server started crashing during nightly backups about a month ago. I tried everything I could think of to troubleshoot the problem and eventually had to give up because I could not keep coming to the office at 4 AM to try to get the server back online. One Friday I got lucky and the server stayed up for its entire full backup. I took this opportunity to restore the full backup to a temporary server I set up and switched all my users to the temporary. Then I reloaded the ailing file server. I kept all my users on the temporary file server for about 3 weeks. I installed the same Backup Exec Remote Agent and Trend Micro A/V client on the temporary server that I was using on the regular file server. During this time, I had absolutely no problems backing up the temporary server. I tested the reloaded file server extensively. I rebooted the server once an hour every day for 3 weeks trying to make it fail. It never did. I felt confident that the reload was the answer to my problems. I moved all of the data from the temporary server back to the regular server. I got 3 nightly backups out of it before it locked up again and started the familiar failure to boot cleanly behavior. This weekend I decided to monitor the file server through the entire backup job. I RDPd into the file server and also into the server running Backup Exec. On the file server I opened the Task Manager so I could view the processes and watch CPU and memory usage. Everything was running smoothly for about 60GB worth of backup. Then I noticed that the byte count of the backup job in Backup Exec had stopped progressing. I looked back over at my RDP session into the file server, and I was getting real time updates about CPU and memory usage still - both nearly 0%, which is unusual. Backups usually hover around 40% usage for the duration of the backup job. Let me reiterate this point: The screen was refreshing and I was getting real time Task Manager updates - until I clicked on the Start menu. The screen went black and the server locked up. In truth, I think the server had already locked up, the video card just hadn't figured it out yet. I went back into my bag of trick: driving to the office and hard reseting the server over and over again when it hangs up at the Windows splash screen. I did this for 2 hours without getting a successful boot. I started panicking because I did not have a decent backup to use to get everything back onto the working temporary file server. Once I exhausted everything I knew to do, I took a deep breath, booted to the Windows Server 2003 CD and performed a repair installation of Windows. The server came back up fine, with all of my data intact. I can now reboot the server at will and it will come back up cleanly. The problem is that I'm afraid as soon as I try to back that data up again I will back at square one. So let me sum things up: Here is what I've done so far to troubleshoot this server: Deleted and recreated the RAID 5 sets. Initialized the drives. Reloaded the server with a fresh Server 2003 install. Confirmed with Dell that I have installed the latest, Dell approved BIOS and NIC drivers. Uninstalled / reinstalled the Backup Exec Remote Agent. Uninstalled the Trend Micro A/V client. Configured the server not to reboot itself after a blue screen so I can see any stop error. I used to think the server was blue screening, but since I enabled this setting I now know that the server just completely locks up. Run chkdsk /r from the Windows Recovery Console. Several errors were found and corrected, but did not help my problem. Help confirm or deny the following assumptions: There are two problems at work here. Why the server is locking up in the first place, and why the server won't boot cleanly after a lockup. This is ultimately a software problem. The server works fine and can be rebooted cleanly all day long - until the first lockup - following a fresh OS load or even a Repair installation. This is not a problem with Backup Exec in general. All of my other servers back up just fine. For the record, all of the other servers run Server 2003, and some of them house more data than the file server in question here. Any help is appreciated. The irony is almost too much to bear. Backing up my data is what is jeopardizing it.

• Windows 7 freezes on boot screen

  - by this is a dead end

  There was some update that required me to restart my computer, so I did. when it restarted, it stays at the Windows boot screen forever, the screen that says "Starting Windows" and has that Windows logo in the middle. I've tried the start up repair program that shows up when I click F8 when the computer starts. And tried system restore but, it says it has restored windows successfully but it still freezes on the boot screen when I reboot it. When I try starting it in safe mode, it gets to the blue Windows background, the one with the logon screen, then says "Failure configuring Windows updates. Reverting Changes. Do not turn off." Then after a while it reboot by itself. Just noticed, the logo animation on the boot screen is still animated. So it's not completely frozen.

• After installing Windows 8, boot hangs before BIOS setup

  - by Joe Purvis

  I have an Alienware M15x, 940MX processor, 16 GB RAM, 512GB M4 SSD, and I was running Win7 64bit. I backed up the disk and ran Win 8 setup. Setup appeared to go well through multiple reboots. After the last reboot, it simply stopped after POST at "Press F2 for bios setup". I have tried powering off, reducing RAM to one stick, removing MOS battery. Now, it gets to the screen with "Press F2 for setup" and "Press F12 for boot options". If I press F2, I get a single beep only. If I press F12, nothing. I cannot get into the BIOS to change boot options to boot from another disk and restore. I do have the latest BIOS. I am going to try replacing the CMOS battery, but I don't think that is likely to help. The computer has been fast and very reliable until now.

• A Windows Update Prevented Live Discs From Working?

  - by user88311

  First off I'll state my system specs. Acer Aspire M1100 Windows Vista Home Basic 32bit OEM 2 Gigs of DDR2 ram 160Gig hard drive 2.7Ghz AMD Athlon 64 processor ATI Radeon X1250 Graphics card A few days ago my computer did automatic updates and updated windows defender to KB915597 (Definition 1.135.415.0), After which when shutting down and starting up I would receive BSOD with the information BUGCODE_USE_DRIVER and 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x877330000) upon where my computer would not start up with any USB devices plugged in and it always require me to run startup repair before it started. Upon when I first started it up and was able to fully boot windows, I had no use of the mouse so I was unable to install the fix that the windows solutions center brought up on my screen, so I restarted again and installed the fix hoping it would cease the problem, it did not. Upoon starting up after installing the fix and restarting I was confronted with the BSOD 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x83291000) at which I found the startup repair could not fix the problem and I restored, as I most like should have in the first place. After going through that I read that simply installing the latest defender version from the microsoft site had fixed this problem for others, so I did that, to find I still received the BSOD's. So in a attempt to find a fix to the problem I went to the microsoft answers site to try to find a way to fix the problem, there I was told to simply disable defender and reboot to see if that fixed the problem, upon doing this my computer would no longer even startup, when I boot normally I get to just when the loading screen finishes and then my computer restarts and when I run startup repair, it runs for about 15 seconds and then my computer restarts as well. I have tried running ubuntu live discs in order to simply access the drive and simply copy and paste the 2 month old physical backup I have of my C drive to the C drive, but whenever I run the live OS when it gets to the end of the load screen and is about to boot, the computer again restarts, yet if I put in a gparted disc, I am able to boot it fully, although it does not give me access to the file system just partition managing and when I attempt to access the internet through it, the computer once again restarts. So my question is, how could the update and what has happened prevent me from running the live OS's properly?

• Will any USB DVD reader work with Apple Mac's?

I had a look around my local PC World today and only the more expensive drives explicitly state on the packaging that they were Mac compatible. Is this just because these products have been through Apple's hardware approval/testing programme, or do Mac's have some special requirement?
