• What to do when Ubuntu 13.10 64-bit does not boot?

  - by Anonymous John

  Ubuntu 13.10 will not boot, it won't even show the grub menu or Ubuntu booting. There is just a purple screen for 20 seconds then a black screen, then the screen says entering power save mode. here are my system specs:Intel DQ965GF Motherboard (OS independant), Intel core 2 64-bit, 12GB HHD (SATA), 200GB HHD (SATA, installed here), 250GB HHD (SATA, Encrypted with LUKS), 3GB DDR2 RAM (DIMM 0 A 1024MB,DIMM 1 A 524MB, DIMM 0 B 1024MB, DIMM 1 B 524MB),2 Rewritable DVD drives (one SATA and one IDE), small floppy drive and car reader, and AMD gallium 0.4. That's all I know from the top of my head, I have no OS to give me more info on the graphics card, but all Ubuntu OSs worked on my PC from 12.04-13.04 just fine. Does this mean will never be able to use Ubuntu 13.10? I think I am screwed.

• Starting old computer - nothing shown on screen at boot

  - by Jonas

  I'm trying to start an about 10 years old PC computer. But nothing is shown on the screen, and it beeps everytime I press a key on the keyboard. I can press Ctrl+Alt+Del to reboot the computer. The monitor is newer and seem to work with other computers. I don't see anything from POST/BIOS at start or later. I have tried to change to another graphic card, but it didn't change anything. What can I do to solve this problem? Update: I have now tried with another computer (the one where the "another graphic card" came from) and I got the same problem. I doesn't show anything on the screen. Both these computers had a GeForce2 MX 400 graphic card. I tried with another computer screen it didn't work - it was showing "signal out of range". So is the graphic card GeForce2 MX 400 too old for newer TFT-monitors? I tried with a third computer so I know that the monitors are working, and both monitors work fine with that computer.

• How do I add pcie_aspm=force to my boot options?

  - by nargo7

  I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

• SSD not detected on boot up running windows 7, with installed blank hdd

  - by Matt. G

  I have recently built a PC for a friend, after the original system build, which included a 60GB primary SSD and a secondary 1TB HDD. I kept getting blue screens of death and kernel power errors, after investigation it was revealed that a faulty power cable and insufficient thermal paste provided with the included heat sink was the cause. This resolved the problem but after 3 months I received a phone call saying that the PC was not starting at the point of loading the operating system, with an NTLDR error. I had an idea of the cause, and after the user removed the HDD the computer started up with no issues, then I asked him to power off and reattach the HDD, and this completely resolved the issue; beforehand even restarting would not fix it. He does not have a surge protector and I thought that maybe some registry corruption had occurred due to a power surge, this might be a stupid answer though. Any ideas to what occurred with the machine would be most appreciated. No other issues have been found since the initial fault. The PC uses Windows 7 Home Premium installed on the SSD.

• Can't Boot Ubuntu, video drivers or x-server problem?

  - by ZacharyH

  I was uninstalling some programs that I installed to try and get my iPod touch working with Ubuntu (I gave up on that) when ubuntu just crashed. Now after I choose ubuntu in GRUB, it gives me a screen that says "Ubuntu is running in low-graphics mode: your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself" It was working just fine before I started to uninstall those programs. I think that I might have uninstalled something necessary to the system. If I click OK on the screen, it gives me options to reconfigure, troubleshoot, exit to console, or restart X. But no matter what I choose I still can't boot into ubuntu - I get stuck looking at the splash screen which stalls forever. I was receiving support from one of my mate's and he was doing something with the LiveCD, and now the message doesn't pop up any more, I just get stuck at a never ending splash screen. Any help would be appreciated, thanks!

• How to boot into Ubuntu after installing into a pre-installed Windows 8 pc?

  - by xVerified

  I recently just installed Ubuntu 13 from a USB drive. I have/had Windows 8 64 bit on my desktop computer. When I restart and boot my computer, there is not an option that allows me to choose Ubuntu, it goes straight to Windows 8. I understand this is a common issue. However, my main question is, how do I get to even GO INTO Ubuntu after it's installed? I don't mind booting into Windows 8 at first, but how can I even choose to see Ubuntu now that it's installed?

• Thin configuration doesn't start on boot, but they do on manual start [migrated]

  - by zad0xsis

  I have some thin config files (generated with sudo thin install) which are slightly modified (only paths where they're located). I can start them just fine with /etc/init.d/thin start, but if the server is restarted, they're not auto started. I issued the update-rc.d thin defaults command to make it run on startup, but no luck yet. This server is running Ubuntu 12.04.1 32-bit, Ruby 1.9.3p194, MongoDB 2.2.0.

• Windows 7 boot error

  - by jason

  I am running windows 7 professional, everything was working fine until I installed a software driver clearner suggested by nvidia customer service and I cleaned only nvidia graphic driver installation since then my windows does not work at all. I can access everything from startup repair, did lots of time repair but nothing happened. System restore does not work it says c: drive is not available, its 100% there and I can access every file from command prompt. Almost two days passed and I applied every solution discussed on several forums, now only thing left is either install fresh windows (Which i really don't want to do) or update windows (which windows does not let me to do, it says I have to update it from windows) My question is there any way to update (not fresh/custom installation) windows from command prompt? P.s: Safe mode, safe mode command nothing works except startup repair option. I ran sfc /scannow no problem found. I also removed all attached hardwares. Any help would be greatly appreciated.

• Hp Pavilion dv6000 wont boot right and freezes

  - by MalwareManiac

  I have an hp pavilion dv6000 that was having windows issues recently including randomly freezing. I eventually concluded that the hard drive was bad (And I was correct as the bad drive started making funny noises and quit working soon after). So I replaced it with a known good drive and put windows on it and it worked for a few hours. After a few restarts startup didn't even make it to the login screen. It just stays at a lighted black screen until I restarted. After another restart it made it to windows but then froze after a few minutes. A few more restarts yielded one of these two results. Like I mentioned earlier I have a know good drive in it and I also replaced the memory that was in it with a know good stick along with running memtest with no errors. So What does that leave? a corrupted windows installation? Motherboard? CPU? Any ideas?

• Can Tutorial "Dual Boot Windows 7 & Ubuntu 12.04" Used for Dual Booting Windows 8 & Ubuntu 12.10?

  - by Shyuan

  I previously used this tutorial to dual boot Windows 7 and Ubuntu 12.04 perfectly. Now I have upgraded my Windows 7 to Windows 8. And I would like to do a fresh install (and start all over again like the tutorial) of Ubuntu 12.10 replacing existing Ubuntu 12.04. I like the way the tutorial presents thus can anyone kindly let me know if the tutorial is compatible with what I wanna do now? I have tried doing little research whether this has been asked, but all I got are not too similar to my question, if there are topics like this I do apologise and feel free to close it. Hope to hear from the community. Thank you so much. :)

• cannot boot ubuntu 13.10 with my usb, Can i change the kernal on my laptop to run it?

  - by Carlos Dunick

  Currently i am running 12.04 and looking for an upgrade to 13.10 I first tried a bootable 64bit usb and failed. With the message saying "Kernal requires an x86-64 CPU but only detected an I686 CPU Unable to boot please use a kernal appropriate for your CPU" then tried 32bit and same message came up. Is this due to my laptop simply being to slow? or can/should i change the kernal somehow?

• Stop UAC/Secure Desktop from dimming the screen

  - by Florian

  I like the concepts of UAC and the "Secure Desktop" in Windows 7, but I don't like the dimming of the Secure Desktop to prompt for Admin credentials (or OK button to get clicked). However, dimming goes so far that my monitor regularly goes into PowerSaver mode, which is annoying (as it takes another 10 seconds for it to wake up), and might harm the monitor: two weeks after switching from XP to Windows 7, my 30" monitor stayed black and it had to get replaced. The web is full of tips how to turn off dimming, but that will always also turn off the "Secure Desktop". Is there a way to present the Secure Desktop without dimming? Or with a different visual effect to show that it is the Secure Desktop? EDIT: To clarify, I'm not looking for a way to disable dimming by disabling Secure Desktop (as is done by lowering the UAC level). I want to keep both UAC and Secure Desktop.

• Dell Latitude will not boot after fresh Ubuntu 12.10 installation. Black screen

  - by James

  I have an old dell latitude d610 that I've just installed ubuntu 12.10 onto, and now unfortunately it will not complete booting up. The screen flashes purple but then fades out and dies. I'm fairly sure there is an issue with graphics drivers, as I had to turn on "nomodeset" in the options when installing off a DVD to see the installer, but I'm very new to linux and don't know terribly much at all apart from what I've read on the net. I have been able to hold down shift and bring up GRUB, and entered into recovery mode, and when I enter into the low graphics mode, the xserver log file says it can detect a screen but found none with a useable configuration, then goes on to say a fatal server error has occurred and no screen have been found at all, telling me to check a log file at "/var/log/xorg.0.log" I have no idea how to check this specific log file! Attempting to actually go further than this in low graphics mode and restart the display simply artefacts the screen. It is all very strange and annoying because I did once by random have the machine boot completely for no apparent reason, but upon restarting the issue reoccurred.

• How do I remove my Windows 7 setup from a Windows/Ubuntu dual-boot?

  - by Tom

  Previously my OS was Window 7 and some day it began to show problems with booting and finally it didn't boot at all. I tried to repair it but it didn't get repaired. Then I installed Ubuntu 14.04 LTS alongside Windows and am impressed much by Ubuntu. So I want to remove all my Windows files. I searched Google to know how to do it and I found OS-Uninstaller. I have some doubts before proceeding with OS-Uninstaller - I need to keep my photos, songs, movies and personal files in my system even if Windows is removed. Normally Windows files are installed in the C Drive. My personal files are not in the C Drive. So will removing Windows files affect my personal files ? Did the OS-Uninstaller affect Ubuntu anyway ? Please note that I want to remove only the Windows installation files(the files added to my system by Windows during its installation). I don't want to change the NTFS partition to any other format since there is a probability that I will install newer version of Windows later.

• Dual boot :Windows 7 partition deleted after Kubuntu 14.04 install...Weird!

  - by user292152

  I've bought two new SSD's in order to install Kubuntu on one and Win 7 on the other one. Before I had Linux Mint and Win7 together one just one SSD. So first I installed win7 as recommended, and then used the guided installer of Kubuntu to install Kubuntu. I selected the second SSD, chose the option "use entire disk and install", but to my surprise after rebooting and selecting win7 boot loader from grub2, I got a prompt that my windows installation is damaged, and I need to run the repair option from the installation disk. So I booted into Kubuntu again, fired up kparted and saw that indeed my windows partition got deleted, except the recovery partition. I don't understand what happened. I am not new to this topic, and this was not my first time installing Ubuntu alongside windows. I have never ever had that problem. What can I do to make sure this won't happen again, so I won't waste another 2 hours of my life? ?? Thanks a lot !

• Is it normal for GRUB to take some time (15+s) after I choose what to boot?

  - by zarnaik

  I had been planning to change the background of my bootloader for a while, and finally got to it. Now the black screen I get for quite some time was made clear. It is still GRUB, because the background image stays, while all of the text is gone. Then it just simply shows the Lubuntu loading screen for, usually, not more than 3 seconds. I run Lubuntu 12.10. My question is, is this normal behaviour or is something going wrong, causing GRUB to take longer? Here are the contents of my grub file located at /etc/default/ : # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND="/usr/share/lubuntu/wallpapers/1210-Windmill_by_Ferran_Reyes.png" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" If you need any other information please tell me and I'll do my best to provide it. :)

• Faster, secure, protocol/code required for long-distance transfer.

  - by Chopper3

  I've ran into a problem and I'm looking for a new secure protocol/client/server that's faster over a 1Gb/s fibre link - let me tell you the story... I have a pair of redundant, diversely-routed, 1Gb/s links over a distance of around 250 miles or so (not dark fibre but a dedicated point to point link, not a mesh). At the 'client' end I have a HP DL380 G5 (2 x dual-core 2.66Ghz Xeon's, 4GB, Windows 2003EE 32-bit), at the 'server' end I have a HP BL460c G6 (2 x quad-core 2.53Ghz Xeons, 48GB, Oracle Linux 5.3 64-bit). I need to transfer around 500 x 2GB files per week from the client to the server machines per week - but the transfer NEEDS to be secure. Using both iPerf or regular FTP I can get ~80MB/s of transfer pretty consistently, which is great. Using WinSCP or Windows SFTP I can't seem to get more that ~3-4MB/s, at this point the server's CPU is 3% busy while CPU0 of the client goes to ~30% utilised. We've tried editing various TCP window sizes with little success. Both ends are connected to quite low-usage Cisco Cat6509's with Sup720's. I can replace the client machine with a newer machine and/or move it to Linux - but this will take time. Clearly these single-threaded secure Windows clients are introducing too much latency doing their encryption. So a few questions/thoughts; Are there any higher performing secure protocols or client software for Windows that I could try? I'm pretty protocol-gnostic so long as it'll work between Windows and Linux. Should I be using hardware to do the encryption, either in the client or the network parts? If so what would you recommend? I'm not convinced that just swapping the server would be that much faster, the CPU was only at 30% but then again that's higher than I'd have expected given the load - moving to Linux at the client end may be a better idea but would be quite disruptive. Am I missing a trick? Thanks in advance.

• How to backup boot information of a PC's Hard Disk?

  - by Bear Bear

  I just installed Windows 7 on a partition of my hard disk and I'm planning to install Vista and Windows 8 on other partitions on the same disk, and maybe a few Linux distributions too. Before I install other Operating Systems, I would like to backup the boot information, just to make sure I can get back to Windows 7 in case anything goes wrong with the booting data. I already made a backup of the MBR using MBRFix but I'm wondering if I should save some Boot Sector from the Windows 7 partition? I noticed that Windows Vista install DVD has a "bootrec.exe" utility in the recovery console (Shift+F10) and it has some options to rewrite the boot sector of the partitions. Therefore I wonder if there is any utility (preferably on Hiren's BootCD) to backup/write the boot sector I would also like to know how to backup the boot data of a Linux installation
