Windows Forum / Windows Me / General Topics / August 2006Invalid system disk
My boot sequence is cd rom/floppy/hd. When I last shut down, I did not take out my floppy disk after saving my work. Now, when I boot up, it says " Boot from ATAPI cdrom - no bootable cd rom...... To start IBM Product Recovery Press F11. Invalid system disk, Replace the disk and press any key" With floppy as the 1st boot and using the WIN98 starup disk, and at A: SCANDISK C: , it did fix something and reports no bad sectors. However, when I try to boot up as per normal (without the floppy) , it still give me the above message " Boot from................ Invalid system disk...........press anay key". Now,how can I get the pc going again withot going through reformatting/recovery path as I need my daya? Thanks system going? Thanks Start the computer with the Startup boot diskette and issue: a:\sys c: John > My boot sequence is cd rom/floppy/hd.

It will transfer the system files to the hard drive and ensure that it (the Hard disk) is bootable. If "sys-ing" the C drive doesn't fix things enter the BIOS and try setting the boot order to the hard dive first and see what happens.

First, if the system is running Win Me it is essential to use a Win Me startup disk rather than one for Win 98SE Second, the command to use is SYS C: and not A:\SYS C: The reason being that the sys command is not on the A:\ drive (floppy) but rather on a RAM drive on the hard disk that is created temporarily when you boot from the startup floppy. If you don't have a Win Me boot floppy download to another PC the image of an OEM Win Me boot floppy from www.bootdisk.com and then copy that image to a floppy by double clicking the downloaded file and following the prompts. Do not simply copy the downloaded image to the floppy.

Is it Windows ME OEM or Windows ME custome no Ramdrive? (Fyi, before my OP. I was doing some scanning and I saw the pc says the D is the Ram drive and E is my cd rom (and there is only 1 partition in my hdd) So does that means I need to doqnload the Windows ME OEM?

Thanks From www.bootdisk.com and downloaded the ME OEM version and extract to a floppy and start the pc and at A:> sys c: and it gives the following message;- "Cannot find the system file in the location on dirve c: Sys can only be used in drive c: to attempt a repair of the already existing installation of Windows. Use Windows SETUP to make drive c: bootable." My c: drive contains 6 files and 9 directories as follows:- [DIR0001} [DISKUN~1] [DISKTW~1] FILE0001.CHK 0003.CHK FILE0004.CHK FILE005 CHK FILE0006.CHK [LOTUS] [MY Docu~1] [My Down`1] (proga~1) FILE0002.CHK [IBMTOOLS] (WINDOWS) Guess something is fishy..... what can I do next? Thanks > Try this one: > [quoted text clipped - 35 lines] > >>>>> > >>>>>system going? Thanks Hmmm. I don't like the looks of all these .chk files on your disk, could be that they have accumulated over a period of time or could be that they were made when you ran scandisk earlier to try and fix things. They indicate attempts to recover bad or broken files from bad sectors on the disk. They could be an indication of a rapidly failing hard disk, something that IBM Deskstar drive are notorious for! If you really want to save files on that disk it might be a good idea to slave the disk in another computer and salvage the files before things go completely to the dogs! Back to the error message from the sys command. Can you confirm the presence of a msdos.sys on the C: drive? Maybe the paths in the file are wrong or maybe the file got completely corrupt or lost. The file is usually hidden, do the following to unhide and edit it: Start the computer with the startup diskette again and at the command prompt issue these commands (press <enter> after each line): attrib -s -h -r c:\msdos.sys edit c:\msdos.sys ***Note the spaces between -s -h -r c:*** If you get "Bad command or filename" you typed it wrong, try again. Now verify the paths in the file. Assuming that your Windows is installed on C: and that it was installed in the default directory the Dir entries should read: WinDir=C:\WINDOWS WinBootDir=C:\WINDOWS HostWinBootDrv=C If the entries point to the wrong paths (=C:\WINDOWS or =C) correct them and try to boot the computer normally again. If the pc doesn't want to boot try the sys command again using the startup diskette. To exit and save the msdos.sys file press the <Alt> key and use the keyboard arrows or letter shortcuts to perform menu actions.

Thanks The reason that you are getting the "Invalid system disk" error is probably because the C:\io.sys file is missing or corrupt. Not having a valid msdos.sys file may be preventing the sys :c command from transferring the files to the hard disk, could be a long shot but other than that my thinking is that the drive might need to be fdisked and reformated to be made bootable again, a procedure that will mean the loss of all data on the disk. You can try placing an msdos.sys file on the hard disk and then do the sys c: command again. Copy the stuff between the === lines below to a notepad file and save it as msdos.sys. Copy the file to a diskette. Boot the computer with the Startup diskette you made earlier. Once booted put the diskette containing the msdos.sys file that you made in the A: drive and when you are at the A:> prompt issue these commands: attrib -s -h -r a:\msdos.sys copy a:msdos.sys c:msdos.sys attrib +s +h +r c:msdos.sys sys c: Keep your fingers crossed... To make the msdos.sys file copy the stuff between these lines (but NOT the ==== lines) ================================================================ [Paths] WinDir=C:\WINDOWS WinBootDir=C:\WINDOWS HostWinBootDrv=C [Options] BootMulti=1 BootGUI=1 AutoScan=1 WinVer=4.90.3000 ; ;The following lines are required for compatibility with other programs. ;Do not remove them (MSDOS.SYS needs to be >1024 bytes). ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxa ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxb ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxc ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxd ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxe ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxf ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxg ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxh ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxi ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxj ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxk ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxl ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxm ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxn ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxo ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxp ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxq ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxr ;xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxs =============================================================================== Note that the last line is a hard return (empty or blank line) and has to be in the file. If that doesn't work I have no suggestions other than trying to salvage your data and trying to reinstall Windows. That is assuming that the drive has not failed beyond recoverability.
