Hallo zusammen
Ich habe auf meinem Thinkpad kein DVD-Laufwerk und möchte Ubuntu deshalb ab einer externen Festplatte installieren.
Ich bin von Windows aus nach dieser Anleitung hier vorgegangen (https://help.ubuntu.com/community/Installation/FromUSBStick).
SYSLINUX is a boot loader that operates off an MS-DOS/Windows FAT filesystem. Most USB flash drives come with a FAT filesystem. Here's how you can add a SYSLINUX bootblock to your USB stick:
Make sure that "syslinux" is installed. SYSLINUX is available for both Linux and MS Windows (the executable is in the archive under \win32\syslinux.exe). For more information check the SYSLINUX homepage: http://www.syslinux.org/. On Ubuntu Linux, install it with:
sudo apt-get install syslinux mtools
2.
Attach your USB stick to your computer and mount it. This may happen automatically. If you are using Linux and it does not get mounted automatically, you can mount it by using a command such as mount -t vfat /dev/sda1 /mnt . Note the mountpoint (i.e. /mnt in the example. If you are using Windows, it should get mounted automatically. (If it doesn't your version of Windows is probably pretty old, and you'll need to install a driver for the USB stick first. Check the vendor's homepage.) Note the drive letter that Windows assigns to it (for example F:).
3.Make the USB stick bootable. If you're using Linux and your USB stick is mounted as in the above example, use: syslinux -s /dev/sda1. If you are using Windows and the flash drive has the letter F: assigned to it as in the above example, use: syslinux -s -m F:
4.You should see a new file called ldlinux.sys in the root directory of your flash drive. (Note that it is a hidden file, you might not see it in Windows Explorer; try dir /a F: from a command prompt). Now you can boot from your USB stick. Read on once you get a SYSLINUX message and a ""boot:"" prompt.
Regarding the IDE disk: When in the USB cradle, the disk is sda, whereas when I mount it in the Libretto as the primary IDE disk, it is of course hda. (I shot myself in the foot a couple of times because of this ...)
The automatic mounting is a bit distracting at times. My recommendation would be to pumount any device you intend to do any low-level operations on, and then mount and unmount as root as necessary. – Era
Make sure to include the -m option with the Windows version of syslinux, to ensure that it copies a fresh ISOLINUX master boot record (MBR.) Otherwise the preexisting MBR may be used, which therefore may not point to your syslinux.cfg file.
Leider erscheint bei mir beim Booten einen "boot"-Prompt, und ich weiss nciht, was ich da eingeben muss. Die Tipps in der Anleitung haben nicht geklappt.
Was könnte ich noch tun?
