You obviously will have to store the backup file on a usb pen drive etc since you are booting from a live CD. Or just store it on the windows partition itself (a bit risky though). Your best bet is probably to use some kind of removable media to store the backup of the master boot record. -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of ?yvind Lode Sent: 5. januar 2010 22:31 To: 'Speakup is a screen review system for Linux.' Subject: RE: Speakup and vinux If you decide to install, backup the MBR (which now stores the windows boot loader) before installing. If you do a mistake with grub you can just restore the MBR and Windows will boot as normal again. Use dd to backup: # dd if=/dev/sda of=windows-mbr.img bs=512 count=1 If you need to restore: # dd if=windows-mbr.img of=/dev/sda bs=512 count=1 When restoring the MBR be sure that you type the command correctly and make sure you don't accidently use a different file. If you accidently dd with a file not containing a MBR, dd will just write 512 blocks from that file to the MBR on the harddrive... That will efficiently destroy the MBR. Also be sure to use the proper device for your HD. /dev/sda may not be the correct one on your system. Most likely /dev/hda if it's an old IDE disk. -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Martin McCormick Sent: 5. januar 2010 22:01 To: Speakup is a screen review system for Linux. Subject: Re: Speakup and vinux It should load just fine as the operating system with speakup appears to take up a couple of gigabytes. The middle-sized ISO image is around 400 megabytes and gives you enough to get started. I remember the painful feeling when I first started using Unix in 1989. It is easy to forget things that now seem second nature but were once show stoppers. If you are familiar with Linux, vinux is standard Debian Linux with speech on the console. If you are new to Unix, find a friend who knows more than you do to at least help you get started. Remember that if you are not root, you can't hurt much except for deleting your own files. There is no undelete that works well as Unix systems are always doing something with files and sectors that you don't need any more are marked as free and the OS may just snap them right up a second later and turn them in to syslog or something else. Unix and all its various flavors like Sunos, AIX and FreeBSD to name a few, don't require defragmentation of the hard drive as they constantly act like a very thorough file clerk in an office who can't stand to see disorder so they are always looking for pieces of files and making sure they all fit together in contiguous blocks so that the OS doesn't have to waste time to gather them from here and there. In other words, when you rm a file, it is often-times gone for good for all practical purposes. The nice thing about a live CD is that you do not have to write so much as one byte to your hard drive in order to test it out. Burn the iso image to a CDROM and boot from that. As long as you don't run the installer, you aren't going to modify your present setup. You will hear it start to talk some time after the boot process starts and you will get a shell just as if you were logged in. Be really careful if you decide to install it as you don't want to destroy your Windows partitions. You can set it up so that you have a short time to decide whether you want to boot Windows or Linux. One thing to watch out for is that the boot sector for Linux mustn't clobber the Windows boot sector. It does sometimes happen. I haven't ever set up a multiple-boot system so I can't help much there The best of luck as you learn about vinux.
