• Trying to boot from usb

  - by iron

  I have similar issues but none with the 12.04 build. Im trying this on a dell d610 laptop with a bad hard drive and was told i could just directly boot from the usb drive. Im using an 8g usb drive and i have tried using the uui tool and get this message. SYSLINUX 4.06 EDD 4.06-pre1 Copyright (c) 1994-2011 H.Peter Anvinet al ERROR: No configuration file found No DEFAULT or UI configuration directive found! Then i tried using unetbootin and got the bootup screen with only the default option and it would say auto boot with a 10 sec countdown and start over again. I do have the boot sequence for usb first.

• USB modem could not mount on 12.04

  - by maz

  I have a usb wimax modem. If I connect it at ubuntu 10.04 it has been detected and mounted as cd see here. From there I got that it is "iso96660" type and device location is /dev/sr1. But when I connect this usb modem in Ubuntu 12.04, it could not be mounted. So I have tried to find the file sr1 in this location /dev/ and could not found any-thing. But if disconnect and then re-connect the usb modem at this path /dev/, I saw a flickering of "sr1" named file for a certain time (1 sec) then it's dis-appear. Can anyone guide me to connect it step-by-step in Ubuntu 12.04?

• Problem with setting up a bootable USB on corrupted OSX

  - by Nick

  I cant access the desktop because my harddrive is corrupted. Therefore I want to make a bootable USB stick so i can transfer all of my important files to my External HD. Problem is that Im stuck on Step 3 --- http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx . Im not sure of what i should change this to: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso It says convert failed - No such file or directory. Obviously the problem is that i dont know the path to the USB, maybe you know how to find out? Please help me. Thanks. ps. Ive downloaded the ubuntu desktop amd64+mac. pps. Unetbootin is a different alternative, but i dont know if it works?

• Create secure working environment on USB stick

  - by Chris

  I want to create an usb stick which contains an ubuntu installation that: can be used as a working environment (Covered in: How do I install Ubuntu to a USB key?) - ie the ubuntu installation on the stick must provide an accessible home folder. Is completely encrypted. I intend to use it as a secure environment to work on sensitive customer data - and also need the system on the stick to be able to connect to the internet. How do I realize the complete usb stick encryption? I am also very thankfull for any further articles and ideas on this topic!

• Lubuntu from USB

  - by WGCman

  I have An Acer Aspire 1362 Laptop with AMD Sompron 2800+ processor and only 256MB RAM, with Windows XP installed. I have downloaded Lubuntu-12.04-alternate-i386.iso and installed it to a 16GB USB stick. I do not want to install Lubuntu on my hard drive (yet!). I have got the USB stick to boot, and am working my way through the menu. At one stage, the installer wants to partition my hard drive, so I abort the installation. There doesn't seem to be an option on the menu to boot and run Lubuntu from the USB stick without putting stuff on the hard drive. How can I achieve this, please?

• USB printer doesn't finish in 12.04

  - by 213441265152351

  I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. Any ideas?

• USB Mouse/Keyboard not working

  - by crstn

  I installed Ubuntu 11.10 after booting it from a USB drive. Everything worked fine there, after booting the keyboard worked in grub but not after Ubuntu was booted. I can unplug either of them and plug them in via a PS2/USB adapter and the device will work. After switching a couple of times, I got the keyboard and mouse both working via usb but after I rebooted either stopped working. How can I fix this? The mouse is a Razer Krait and the keyboard is a Logitech ClassicKeyboard 200.

• Why is using an external USB drive or USB printer causing my system to hang?

  - by thepd

  I am having some troubles using various external hard drives and my printer, all of which I connect using USB. The majority of the time, when I connect either of these devices, my system freezes up completely after about 10 minutes. They work just fine prior to that moment. I've also not noticed any problems using a USB mouse. I'm running Ubuntu 10.10 and have tried using a newer kernel (a 2.6.36 Maverick kernel from the kernel ppa, as opposed to the default 2.6.35 one) to no avail. I'm using a Dell Studio XPS 16 (M1647) which is a sort of newish laptop and so my guess is this is probably some kind of driver bug. Is there anyway to debug these sorts of issues? I've looked through some of my logs (/var/log/messages seemed the most useful) but haven't been able to find any kind of USB related logging nor anything interesting happening prior to the hang.

• Trying to boot from USB on Asus q200e-bhi3t45 just brings me to grub menu

  - by Krash Kharma

  It's been a struggle every time I've tried to change my OS on this machine. I honestly don't even know how it works whenever it does. I've somehow managed to get Windows 7, Windows 8, Mint 14, Ubuntu 12.04, and 12.10 to work at random times but it's always after struggling with it and googling for random chance fixes and suddenly something clicks and it loads from usb, but 99% of the time, every time I try to boot from USB to install a distro (in this case, I'm trying to get ubuntu-12.04.2-desktop-amd64.iso to work) my pc just comes up with a grub menu ("Minimal bash-like blahblahblah - grub ") I don't know why it works when it works. Right now I've tried everything from with/without Fast Boot in BIOS, with/without CSM, with/without secure boot, to changing BOOTx64.EFI to bootx64.efi to downloading a new bootx64.efi to copying it to every folder on the usb.... It makes no sense to me. Sorry if this has been asked before but I can't find anything

• usb drive filesystem?

  - by purbleguy

  So, school is approaching quickly, and one of the things on my supply list is a usb drive. Now I'm asking myself what filesystem to use. After some research, I found ext4 to be the most stable drive filesystem. But, I also found that Windows (The OS used by every computer in my school) can't read ext4 formatted drives without special drivers, and I'm sure the school wouldn't be too happy with me having to install the windows ext4 drivers on every computer I use with my usb. So, my question is, Should I use fat32, one of the ext filesystems (2, 3 or 4 would work) or NTFS, I have an ubuntu laptop, a Mac desktop, and of course the school computers I use are Windows, so which would be the best filesystem for my usb.

• How to install Ubuntu using a USB stick?

  - by J. N.

  I cannot install Ubuntu 11.10 from a USB stick. It doesn't boot to Ubuntu page for installation but remains on Windows 7. I've downloaded the 11.10 version iso file and burnt it to a USB stick. After I inserted it, the USB stick is a symbol of Ubuntu installation and I clicked wubi to try to install it. But it didn't boot to Ubuntu but stayed on Win 7 after restart. It occurred error and said "windowsBackend" object has no attribut "cd_path" when I chose "Help me to boot from CD". I thought it's the problem of my computer model (acer travelmate 8481), but it can't boot on an old computer using XP as well. How can I solve this problem and install Ubuntu to replace Windows?

• USB key will only be mounted by gparted [?]

  - by user2413

  Hi, When I insert by usb key nothing happens (i.e. the drive is not visible). I can mount the USB drive from gparted though (and then it's suddenly recognized). It's not particular to any USB key. This only happens on my laptop (on the desktop the same key will be mounted upon plugging it in without any problems). Finally, the key is formated as fat32 and dosfstools and mtools are installed (through gparted claims otherwise). what's the catch? EDIT Also, gparted offers me the option to mount the key on "/" : shouldn't that be "/media" (or has this changed ?)

• unable to boot from live USB!

  - by ramblinman

  Linux noob here. I was messing around with my new dual-boot (win7 and the latest ubuntu, 12.04 I think?) Long story short, I deleted some partitions that I shouldn't have. When I boot up the machine, I get: error: no such partition. grub rescue _ I know that I could probably fix this by booting from the live USB. But I can't boot from the live USB either! On startup, I can get "boot from drive" options by pressing F12. (This is how I installed Ubuntu in the first place.) But when I select the USB drive, I get this error: error: no such device: [long string of letters and numbers]. grub rescue _ I've searched around for a fix but most threads addressing the first problem suggest booting from live drive. And I can't do that! Any help much appreciated.

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• Ubuntu 12.04 won't boot from USB

  - by user986871

  I downloaded Ubuntu 12.04, then using the tool Startup Disk Creator i made the live usb. I checked that it's bootable Device Boot Start End Blocks Id System /dev/sdb1 * 62 15635593 7817766 c W95 FAT32 (LBA) Now on my lap top it boots nicely, but on two other machines that don't have any installation of ubuntu(no Grub) it doesn't boot. I changed the booting order so that USB is before HDD. So i think i did everything i know, but no luck. How can i use this USB drive on other devices that don't have any previous ubuntu installation.

• What to do about USB support?

  - by RhZ

  USB speeds are consistently slow in ubuntu, and have been for years. I just bought two new machines with usb 3.0, running 10.04, and yet nothing has changed, top speeds are only about 8.0 MB per second and they quickly drop to 2 or less. Its very frustrating. Are there any fixes for this at all? I find almost nothing online. The board is a gigabyte 970A-DS3 motherboard. Is there any driver I should install? I am using brand new usb sticks (kingston) and making sure to plug into the 3.0 (blue) slot.

• 100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

  - by Will3265

  On my server I am trying to install a new usb drive but all that happens is that the system starts using huge amounts of processor cycles with services.exe. On closer inspection with process explorer there is a thread called umpnpmgr.dll using most of the services.exe processor time. I left it for a half hour and still nothing happened. Rebooted and tried again, same result. Tried a different usb drive, then a flash drive but still same issue. Tried updating driver but it said the update function was already in action. I have used process explorer to kill the thread now so the server can still perform its intended functions. Any device that was previously installed before this began happening will still work but any device new to the system will not. My question(s) is/are: Is there a way to manually install the device into the registry so Windows thinks it is a previously installed device? Or can this problem be repaired through anything other than a reinstall? To do a reinstall would mean backing up large amounts of data which is hard with a usb drive and insufficient space on all other network machines. Any help would be greatly appreciated. William

• Windows Server 2008 R2 Print Server - Change Printer Names on All Client Systems

  - by Jeramy

  I have a Windows Server 2008 R2 print server set up hosting out multiple printers to my end users. I would like to change the naming convention for all of the printers hosted on the print server and want this change reflected on the client end. For example: I have a HP4000 printer named "Cottage" on the print server. I want to rename the printer "HR-1stFloor-220a" on the print server and I want this printer to appear on every client system with the new name. Simply renaming the printer on the server automatically creates a link from the old printer name to the new one, so all the clients work but the actual name, from their perspective, has not changed. Renaming the share name also does not visibly effect the end user (though it does update the port information). I would like to have the names of the printers be meaningful information regarding department and location, but this means that when they change hands or move I would need to update this information, and currently I am not seeing a way short of writing custom start-up scripts and remove/replacing them through AD. Is there a simple way of accomplishing this task? Thank you for your help.

• Migrate Domain from Server 2008 R2 to Small Business Server 2011

  - by josecortesp

  I'm looking for some advice here, rather than the big how to do it I'm looking for what do to I have this home server, quad core and 4 GB of ram (I really can't afford more right now). With a Windows Serve 2008 R2 With ActiveDirectory and a Hyper-V-Virtual machine with SharePoint, TFS and a couple of more thigs. I have a least 10 remote users, all of them joined a Hamachi VPN (working great by the way). But I want to migrate that to a Small Business Server 2011 Standard. I tried to make a VM to join the domain and then promote that VM, back up it and then format the physical server, boot up the VM, Promote the Phisical and then erase the VM, but I can't do that because of SBS requiring a least 4 GB of ram to install (so I can't give all the 4 GB of physical ram to a VM). I was thinking in using a laptop (All the clients are laptop) as a temporal server, join the domain, promote it, then format the server and install SBS on the server and do all again. I really need some advice. Thanks in advance. BTW, I know that the software I'm using is kindda expensive, and I can't afford more hardware. I have access to MS downloads by a University partnership so I have all this software for free.

• Limit the number of rows returned on the server side (forced limit)

  - by evolve

  So we have a piece of software which has a poorly written SQL statement which is causing every row from a table to be returned. There are several million rows in the table so this is causing serious memory issues and crashes on our clients machine. The vendor is in the process of creating a patch for the issue, however it is still a few weeks out. In the mean time we were attempting to figure out a method of limiting the number of results returned on the server side just as a temporary fix. I have no real hope of there being a solution, I've looked around and don't really see any ways of doing this, however I'm hoping someone might have an idea. Thank you in advance. EDIT I forgot an important piece of information, we have no access to the source code so we can not change this on the client side where the SQL statement is formed. There is no real server side component, the client just accesses the database directly. Any solution would basically require a procedure, trigger, or some sort of SQL-Server 2008 setting/command.

• Database Mirroring of SQL server

  - by jbp117

  I have two databases that are mirrored to another server using database mirroring. The mirror server has to be down for some reason for few days. Now the production server is having principal databases in (PRINCIPAL/DISCONNECTED) State. Clients can access those databases. So what happens when they keep on adding data to these databases?? Will the data get committed or waits till the mirror comes up?

• SQL Server instance shuts down

  - by user42119

  I'm currently developing a new ASP.NET project hosted on a Windows Server 2008 RC2 with an SQL Server 2008 Express database. I have three SQL Server instances (for different purposes) running which currently all contain a single database. For apparently no reason, these instances tend to shut down after some days. There might be low or no traffic to these instances, because there might be some days in a row, where I can't develop. It now occurred several times, that one or two of these three instances just shut down, so that I can't access the database, without manually starting the instance. I can't seem to find a event log entry for the shutdown, which is most likely because I just enabled logging (why is the default setting off?). So the questions are: * Why does an SQL Server instance shut down? (Is there such a thing as a "Shut down instance after 3 days of inactivity"? * How can I achieve that the instances are running 24/7? Edit: I solved this problem by writing my own application that checks for the status of the SQL Server services. My program will start via a batch file, that gets called by the Windows Task Scheduler every 5 minutes.
