Linux boot process with GRUB Netbooks, Notebooks, Windows and Linux » Sep 13 2008 12:26AM GMT Grub and boot error 27 unrecognized command errors John Little Profile: Xjlittle Tags: Thanks! We'll email youwhen relevant content isadded and updated. Following Follow Storage If you've administered or customized Linux long enough you've no doubt created a situation
at some point where, during the boot process, that GRUB throws an error. We're going to discuss some of these situations below along with ways to work through them. If a file name or partition in the GRUB configuration file is incorrect GRUB won't be able to find critical files such as the Linux kernel. For instance if the root directive points to something lỗi error 27 unrecognized command other than the /boot directory GRUB will throw one of the following errors:
Error 17: Cannot mount selected partition
Error 27: Unrecognized command
Error while parsing number
Cannot mount selected partition
If the GRUB configuration file is completely missing you will see the following:
If you find yourself at this prompt you can find a list of available commands by hitting the tab key. The first thing that you are going to want to do in any of these cases is check and make sure that your root directive is correct. To do this, at the grub prompt, use the find command to locate the GRUB configuration file. Your search would begin something like this:
grub> find (hd0,0)/grub/grub.conf
where hd0,0 is the 1st hard disk and the 1st partition on the hard disk. Repeat the process using the various partitions on the 1st disk (hd0,1 hd0,2) and so on until you find the configuration file. If the partition is not found you will get an error:
Error 15: File not found

I was running Gutsy and XP, booting using Grub. Anyway, I upgraded to Hardy over the weekend, deciding to tidy up my partitions to increase my linux install space to allow for a VirtualBox. I deleted my original partitions, using the Live CD & gparted, then created 2 new ones for / and /home. Installed Hardy and that boots fine. When I try to boot to XP though I get Error 27: Unrecognised command. Have followed some threads which suggest refreshing grub, following: Code: find /boot/grub/stage1 reports hd0,6 Code: root (hd0,6) Code: setup(hd0) But whenever I get to setup(hd0) I get another error 27! Any help to get the beast of XP back to life would be appreciated.... My

Dear Nate, Thanks http://www.wilderssecurity.com/threads/yumi-and-error-27-unrecognized-command.326319/ for such nice explanation in PM. I have no problem using xBoot and http://reboot.pro/topic/19129-grub4dos-set-command-is-unknown/ adding all my WinPE and Linux ISOs to it. However, when it comes to YUMI. The Linux ISOs which are listed in the menu work. However, when I install the WinPE ISOs, they don't work. It gives the following error: "Error 27: Unrecognized command." On Google, the error has to do with error 27 menu.lst. I cannot upload this file for you in PM. I have opened this thread and upload here, so that you can have a look. The ISO is under the directory, Mulitboot/ISOS Best regards, KOR! P.S. I have renamed the menu.lst to menu.txt for uploading purpose!

I do know that there were changes in this latest build that would have caused boot errors unless you formatted your drive before using (or followed the instructions I gave you). That could be the issue. Also possible is that there is something special to the Macrium Reflect PE discs that others don't have. I have no idea about that as I only use custom built discs. All custom DVDs, when added to Yumi, are put in Mulitboot/ISOS, all entries made to menu.lst. So we know that the ISO is being copied right. And the menu.lst appears to be correct. If that is true, process of elimination says it's the PE disc. Try anther PE disc (if you can) to see if that's the issue.

There are many reasons why Error 27 Unrecognised Command happen, including having malware, spyware, or programs not installing properly. You can have all kinds of system conflicts, registry errors, and Active X errors. Reimage specializes in Windows repair. It scans and diagnoses, then repairs, your damaged PC with technology that not only fixes your Windows Operating System, but also reverses the damage already done with a full database of replacement files.
A FREE Scan (approx. 5 minutes) into your PC's Windows Operating System detects problems divided into 3 categories - Hardware, Security and Stability. At the end of the scan, you can review your PC's Hardware, Security and Stability in comparison with a worldwide average. You can review a summary of the problems detected during your scan. Will Reimage fix my Error 27 Unrecognised Command problem? There's no way to tell without running the program. The state of people's computers varies wildly, depending on the different specs and software they're running, so even if reimage could fix Error 27 Unrecognised Command on one machine doesn't necessarily mean it will fix it on all machines. Thankfully it only takes minutes to run a scan and see what issues Reimage can detect and fix.
A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
Reimage repairs and replaces all critical Windows system files needed to run and restart correctly, without harming your user data. Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.
Reimage patented technology, is the only PC Repair program of its kind that actually reverses the damage done to your operating system. The online database is comprised of over 25,000,000 updated essential components that will replace any damaged or missing file on a Windows operating system with a healthy version of the file so that your PC's performance, stability & security will be restored and even improve. The repair will deactivate then quarantine all Malware found then remove virus damage. All System Files, DLLs, and Registry Keys that have been corrupted or damaged will be replaced with new healthy files from our continuously updated online database.
