Is there a way to trick the system to boot? (somehow ignore different checksum or

something) Thanks in advance. Also, how come and UBCD4 is so much smaller than UBCD3.4? Was the overhead so different? _________________--- NLS Top Constance Post subject: Posted: Tue Mar 13, 2007 7:10 pm Joined: Fri Sep 23, 2005 1:21 amPosts: 338Location: France If I remember well, Insert has been removed starting from version 4.

Is that of initial bootup or one of the folders? Top nls Post subject: Posted: Mon Mar 19, 2007 11:55 pm Joined: Wed Dec 27, 2006 11:51 amPosts: 14Location: GREECE What you mean? I found the total size of the image much smaller. Probably because of INSERT. Or you mean about the checksum error? I have a triple boot CD, where all three "original" CD folders are dropped on the new CD (luckily there is no real folder conflict) and extracted the original boot code
while booting Isolinux Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi, > makehybrid \ > -o isos/muaaa.iso temp/ \ > -eltorito-boot temp/isolinux/isolinux.bin \ > -no-emul-boot \ > -iso -joliet -boot-load-size 4 \ > -default-volume-name "Custom Installer" \ > -eltorito-platform temp/isolinux/boot.cat > ... > [at boot time:] > Image checksum error, sorry http://www.ultimatebootcd.com/forums/viewtopic.php?t=847 I guess it is the Boot Information Table feature that's missing with your ISO production run. The boot image isolinux.bin expects to get patched by some parameters, including a checksum. See man mkisofs http://cdrecord.berlios.de/private/man/cdrecord/mkisofs.8.html paragraph "EL TORITO BOOT INFORMATION TABLE" Do i get it right that http://www.syslinux.org/archives/2013-November/021111.html "makehybrid" is a shortcut for hdiutil makehybrid as of https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/hdiutil.1.html There seems to be no option for above feature. Programs which can produce compliant ISO images are: program="mkisofs" program="genisoimage" program="xorriso -as mkisofs" Use one of them instead of your ISO production command: cd temp $program \ -o ../isos/muaaa.iso \ -b isolinux/isolinux.bin \ -c isolinux/boot.cat \ -no-emul-boot -boot-load-size 4 -boot-info-table \ -J \ -V "Custom Installer" \ . I read in man hdiutil that -eltorito-platform gets a parameter like 0. How come yours gets the name of the boot catalog ?

error in WinRAR file? Nowadays, people tend to store more and more data on their computer's hard disk. And, in order to save memory space, they compress these files in WinRAR format. RAR compression technique helps users to save http://www.remorepair.com/help/how-to-fix-checksum-error-in-winrar-extraction.html a lot of hard disk space and make tasks like transferring, downloading, uploading, emailing much http://askubuntu.com/questions/38778/checksums-do-not-match-when-creating-a-bootable-usb-stick easier. However, it is really frustrating situation for users when they encounter errors while extracting contents from a WinRAR file. More often than not, the error message would be CRC. So, what is CRC error? CRC stands for Cyclic Redundancy Check, it is an error notification usually encountered while WinRAR file extraction. CRC is an algorithm which checks the checksum error checksum bit of the source and downloaded WinRAR file, if this checksum of your RAR file doesn’t match up then it’ll result in CRC error notification. Sometimes, no matter how many times you try, you won’t be able to access any of the contents from the WinRAR file. There are several causes due to which you end up with CRC error, some of them include: Download interruption of WinRAR files due to reasons like power isolinux image checksum failure, network inconsistency, etc Deadly malware / virus infection on WinRAR file Bad sectors on storage media where WinRAR files are stored Extracting the contents of WinRAR using unreliable third party applications Other reasons include improper recovery, file system corruption, transfer error, OS reinstallation, etc Techniques to fix checksum error in WinRAR file: There are three ways to eliminate checksum error in WinRAR file, just follow the below procedures and know how: Method 1: Try re-downloading the whole WinRAR archive file from the internet again. If it is still available, sometimes re-downloading the file will help you eliminate the problem. Method 2: If the first method didn’t help you, then overcome CRC error using WinRAR application Right click on the corrupt / damaged WinRAR file and choose “Extract files” options Tick on “Keep Broken Files” check box under Miscellaneous tab Choose the folder where you want to save the extracted files and click “Ok” button And while the extraction process if any CRC error pops up. Simply click “Close” Nevertheless, if both this method fails in extracting the contents from your WinRAR files; then you need to download and use powerful WinRAR repair software such as Remo Repair.

Always the same error, it arrives to 96% and then this error " checksums do not match". Also in lucid, meerkat and natty even with fresh install. Tried it with more than USB stick. Am I doing somthing wrong? I did format the USB stick several times but no luck. It's 2Gb. Now I lost my DVD drive on my laptop, and USB is my only option. Please help! I did try different USB sticks I did try unetbootin, with success, but when booting from USB and selecting check disk for errors within the unetbootin menu it gives me 1 error, so I didn't try actually to install the O. S for precaution reasons. I did try to launch disk creator from terminal with sudo and that gives the same error on 96% of the process. doing the check proposed by chen xiao-long, the codes result no match. suliman@suliman-laptop:~$ sudo mount -o loop /home/suliman/Documents/ubuntu-11.04-desktop-i386.iso /mnt [sudo] password for suliman: suliman@suliman-laptop:~$ md5sum /mnt/casper/filesystem.squashfs 174bb50daab963e681d2dcd9603f737b /mnt/casper/filesystem.squashfs suliman@suliman-laptop:~$ md5sum '/media/8BE1-C58A/casper/filesystem.squashfs' e4129f8ff21860d978c911b3b394f807 /media/8BE1-C58A/casper/filesystem.squashfs if the usb port is faulty, how can i check that? 11.04 usb-drive disk usb-creator share|improve this question edited Apr 29 at 3:34 muru 69.1k12125176 asked May 1 '11 at 11:36
