The partition of type 21 spanning over the last cylinder makes me think of a drive that has been used with RMPREPUSB/Easy2Boot. The partition table in the MBR is "strange". PBR (the drive was partitioned under XP or earlier, in any case it is a "63 sectors before":ħ7 004D Volume Serial: 20202045 538976325

Once you have the files, zip them together in an archive and either attach it to your next post or upload them to a free file hosting site and post a link to the archive.Įntry Typeěoot bCyl bHead bSect eCyl eHead eSec StartSector NumSectors I need a copy of the MBR (first absolute sector or LBA0) and of the PBR (either sector LBA 63 if partitoned under up to XP or LBA 2048 if under Vista or later, do both as it costs nothing).ĭsfo \\.\PhysicalDrive4 0 512 C:\myfailed.mbrĭsfo \\.\PhysicalDrive4 32256 512 C:\myfailedxp.pbrĭsfo \\.\PhysicalDrive4 1048576 512 C:\myfailed7.pbr Or, are you familiar with command line tools? dsfo/dsfi part of the dsfok toolkit are generally recommended by me: Ideally you could use a hex/disk editor to save a copy of these two sectors. Unfortunately partition wizard (while generally being a good tool) has not the "level of detail" needed to analyze the issue.Ĭan you make a backup of both the MBR and of the PBR? Well, then we need to first recover the volume/partition and only later the ldlinux will be needed to be fixed. Someone must tell the good guy over there how "older" and "newest" are pointless adjectives when talking of programs, particularly if the program (rightly) uses versions, such as the current YUMI-2.0.6.1a.exe, in any case, if you can find on the USB the file libcom32.c32 it is the "newest", otherwise it is the "older". YUMI will notice that this file is missing and will attempt to repair it.

Once finished, rename _libcom32.c32 back to libcom32.c32.ĭelete the hidden ldlinux.sys file from the multiboot folder, and use YUMI to install any menu item. YUMI will notice that the file is missing and will attempt to reinstall syslinux and repair the master boot record. This is useful if your YUMI prepared USB drive is somehow no longer bootable.įrom the multiboot folder on your flash drive, delete the hidden file ldlinux.sys and then rename the libcom32.c32 file to _libcom32.c32.

How to force a rebuild of the Syslinux MBR:

Usually it is not an issue to just re-install syslinux:īut it has to be sen which exact version of syslinux is used and possibly Yumi is using "non-standard" directory structure, so it would be better to repair the Yumi, it has to be seen as well which exact version your Yumi USB is (was) running, see here: So what may have happened is that the ldlinux.sys has "wrong" information I am not familiar with YUMI, AFAICR it uses syslnux "under the hood" as "main" bootmanager.

Is there a way to fix the partition table on the usb? Maybe using diskpart, because my laptop has Windows 7, but i also could use other software or live cd, just don't know which. My guess is that the partition table is somehow damaged during the partition resizing operation, and i didn't backup the partition table before using GParted. I have multiboot usb created with YUMI and i used GParted Live to resize the partition on the usb, shrinking its size, but after that the usb won't boot.
