![]() ![]() In the case of very old computer systems with 4:3 aspect monitors, the graphical user interface can also be started in SVGA or XGA resolution. To avoid problems with the graphics card, the distribution also integrates a standard VESA graphics driver. The system can also be copied completely into main memory and operated from there, which has advantages for very old and correspondingly slow computers. When starting the Live system, the GRUB boot manager ( Figure 1) welcomes you with numerous options that include different kernels for different Intel hardware architectures.įigure 1: SystemRescueCd offers a variety of startup options, including the ability to launch various floppy disk images. Replace the drive information sd in the copy command with the correct device name for the USB storage medium used. $ sudo dd if=systemrescuecd-x86-.iso of=/dev/sd bs=1M To boot the operating system from a USB stick, use the commands: $ isohybrid systemrescuecd-x86-.iso ![]() The entire distro fits on a CD, so it is also suitable for use on older systems. The Gentoo derivative is a hybrid image for 32- and 64-bit computers that comes in just under 470MB. SystemRescueCd can help in these cases by providing a comprehensive toolbox for every computer, with the possibility of restoring lost items. Once the milk has been spilled, the anxious search begins for important photos, videos, correspondence, and spreadsheets. As a result, users are storing more and more data on local storage media – often without worrying about backing it up. The simplest way to dual boot Windows (or MS-DOS) is to add an MBR menu entry to GRUB2's grub.cfg file for each Windows operating system installed.įor instance, to boot Windows 7, add the following to the grub.The price for mass storage devices of all types has been falling steadily in recent years, with a simultaneous increase in capacity. Sometimes it is necessary in the BIOS firmware configuration tool to disable UEFI mode completely in order to force BIOS MBR mode. Manually create a MSDOS partition layout, then manually boot the Windows DVD using a BIOS option in the boot menu list. In order to specify Windows 8 (and above) to use MSDOS partitioning the Windows installation DVD needs to be booted in BIOS mode (a non-UEFI boot mode) in order for Windows to install into MSDOS partitions. Microsoft Windows 8 (and above versions) are no longer installed using MSDOS partitions by default, however they do maintain backwards compatibility with BIOS MBR systems. However, if Windows is on the same disk on a different partition, or if regular chainloading doesn't work, then read on. When Windows (or another MS DOS based boot loader) is installed on another disk, then regular chainloading in the grub.cfg may be sufficient to boot it. Then have GRUB2 installed on the partition instead of in the MBR itself so that GRUB2 is chainloaded. GRUB4DOS has an interface very similar to GRUB Legacy and a menu.lst entry which can be used to chainload the TrueCrypt bootloader or to boot a rescue CD (from an encrypted partition on the same disk).Īnother workaround is to boot from TrueCrypt as the main boot loader and then hit the Esc to chainload the following partition (if one exists) or the following disk. Use either GRUB Legacy or GRUB4DOS as workaround. The mapping is necessary before chainloading TrueCrypt bootloader in the case that the boot disk (hd1 as shown in the example above) should appear as the primary boot device (hd0), otherwise TrueCrypt would fail to boot because the correct disk will not be found.Ĭhainloading a disk with TrueCrypt in the MBR or a rescue CD image located in encrypted partitions is not possible with GRUB2 (see bug #385619). ![]() The remapping may not be necessary if the system has a single boot disk. To chainload an ISO with custom or default kernel command line arguments, an entry similar to the following can be added to GRUB2's grub.cfg file: No more need to listen to a whining CD/DVD drive on each new command! This makes it possible to have a handy way to install an operating system with everything in RAM, especially for "light weight" LiveCDs. Gentoo liveCD is handy because it has a minimal shell which lets the user mount the squashed image to the correct location and then press the Esc key to continue the boot process. Without kernel cmdline options, booting ISO images with GRUB2 will fail in the physical media check/test stage of the ISOs boot process. In any case, the ISO images in question should be built keeping kernel cmdline arguments in mind. It is possible to chainload ISO images (LiveCD/DVDs) with GRUB Legacy, however there exists no way to pass kernel cmdline arguments before boot. The new ISO (or loop) chainload mechanism makes chainloading a breeze. ![]()
