That disc should be able to boot up off of the cd once you turn on your laptop. ON your toshiba press F2 to go into the BIOS and change the boot options, make sure it boots up off of the cd-rom first. Put the os cd in then go ahead and save the changes and exit. The F10 key should allow you to save the changes and exit the BIOS. Once it reboots then if its booting properly, it should tell you to "Press any key to continue". Then it will go into cd and boot up and load a fresh copy of the OS.

Also make sure before putting your cd into the drive that there is no dirt or fingerprints on the cd or else the laser won't read the cd.

If you need any other help, let me know.

Samsung r530 bad sector hard drive. Did not come with operating software disc.

Remove the HDD and test, replace if necessary. You can contact Samsung, with your laptop Serial Number, and purchase a Factory Recovery DVD. Or, you can buy a Windows Installation DVD and do a Fresh install on the new HDD.

Recovery discs aren't working on my hp cq60-615dx, what should I try next?

Appears that recovery disk #2 is bogus. U can try to get a new set from HP (fat chance!) or you can do a reload from a normal, retail OS disk.

My Asus F9e doesnt start anymore. Not even in Secure Mode. What should i do ?

Did you get any error messages? Since the BIOS is available, the problem is likely with the hard drive or it's trying to boot from non-bootable media (DVD, flash drive, USB connected floppy/hard drive). Since you can access the BIOS, look for the Boot Selection Order and make sure that the hard drive is first in the list. If the BIOS doesn't see the hard drive, it may be bad or have a bad power or data connection. (You can try opening the computer and reseating the cables - see Asus for any assistance. I am not informed on opening the F9e.)
If the hard drive is seen by the BIOS:
Disconnect any USB devices (and the optical disc if it is in the drive). Turn off the computer. Unplug the notebook from the power supply and remove the battery. Wait 10+ seconds (or a few minutes) then reconnect the battery and then the power brick. Try restarting the computer. (This is a hard reset.)

What do you see on the computer screen? If you see a blinking cursor, the computer doesn't have the boot manager available (either corrupted or a new disc that hasn't had the OS installed). Use a Windows install/upgrade disc/system repair disc for your OS version (the service pack must match) or a third-party disc management tool to attempt to repair the boot manager.

You will need the optical drive as the first boot device in the BIOS or press Esc to access boot order list. (On some computers, it's F12.) For Vista or Win7, boot from the CD and follow the on-screen directions until you see a list of choices. If the hard drive was previously working, click on Repair your computer. Select the OS to repair then click Next. Select the Command Prompt option. Type in bootrec /ScanOs to get a list of available Windows OS versions on the hard drive. Use the command bootrec /FixBoot to fix the master boot record. The command bootrec /RebuildBcd will rebuild the list of Windows OS versions. See for details.

Installing a new hard drive and reinstalling the OS may be needed if you have a SMART or AHCI/SATA hard drive error. If you have a back up image, you may be able to restore that image.

I hope this helps. Please add a comment with any error messages for more assistance.

There are several issues that can cause this err1err3 issue. It could be a bad hard disc (or a bad wire between the drive and the motherboard), an incorrect BIOS setting for the SATA hard drive or a problem with the master boot record (MBR). Make sure that there is no disc in the CD drive and disconnect any external storage devices (flash drive). Your computer may be trying to boot from a non-bootable disc.

To check the BIOS setting, turn off the computer and turn it back on. Press F10 continuously to access the BIOS on an HP computer. Some HP computers use F2 or F6. There should be a splash screen that tells you which to use. (If you see the error again, try this step again. It's easy to not have the key press noticed between the POST and the attempt to boot the computer.) Once in the BIOS, go to the Advanced Settings tab (one to the right) and go down to the SATA1 controller option. (Try AHCI.) Then press F10 to save and exit. (Note this isn't part of the BIOS on all HP machines - it does work for some.) See if there is a Diagnostics tab in the BIOS and try running the hard drive test.

Get an hard drive testing utility (ISO) and burn it to CD on another computer. You can set the first boot location when you go into the BIOS as above. With the bootable CD in the drive, restart the computer. (Some machines let you set the one-time boot location by pressing F12 on start up; as with entering the BIOS, it's easy to miss the timing. Just repeat the attempt.)

If the disc tests as good, you can try to repair the MBR. Use a repair tool or an OS install disc for your version of Vista (Home Premium). Boot from the CD as above. With the install disc, follow the on- screen directions and select the Repair option. You will need to enter the Command line mode. You'll need to enter Bootrec with the correct option. For more information, see the following document: .

If you possibly can, remove the drive from your current computer before trying the repair. Use a USB/IDE/SATA adapter and another computer, see if the data on the disc can be copied to make a back up. This will work if the disc is still good. (It will also indicate if the cable was the problem if the disc failed the diagnostic tests.)

I hope this helps.

Laptop wont start up just says a disc read error has occured, press Ctrl+Alt+Del to restart but when I do this I just keep getting the same message

Two possibilities are involved. 1) The hare drive is not responding correctly. This could result from a loose cable (needs to be connected to the motherboard and the drive) or a damaged drive (either from damage to the disc or lost boot information).
2) A non-boot disc is being accessed in the boot sequence. This could be a CD/DVD in the optical drive, a floppy disc in that drive (older laptops) or a USB connected drive (either a thumb drive or a regular external disc).

The second issue is easy to solve, disconnect/remove any other media. Then try to boot. Alternatively, on most Windows machines, you can press F12 to choose the boot sequence. However, you need to press the button between the POST (power on self test) and the loading of Windows. For me, this can take several attempts.

For the first, the options depend on your skill/willingness to open the computer. One option is to use a Live CD (a bootable disc) to see the status of the hard drive. Use the F12 sequence if needed to boot from the disc. (The live cd could be a Windows Recovery/Install disc.)

To save files from the disc, you can either use a UNIX Live CD and an other drive (an external optical R/W drive or hard drive) or remove the disc completely and connect it to another computer. For this second option, use an IDE/SATA/USB dongle, a laptop hard drive enclosure or hard drive dock. The dock will work with a SATA drive; disc enclosures need to be selected to match the drive type (IDE or SATA). When you do the disc removal, you will see if the cables are loose. Be careful with static while opening the computer.

Then replace the drive with a new one, reformat and reinstall the OS or use the recovery disc to attempt to fix the boot problem.

I hope this helps.

My mac air stays on grey screen how do i get it to boot !

Insert your Mac OS disc and start your laptop with the c key held down. It will launch the system on the disc instead of your computer. Once it reaches the desktop, you can choose "Disk Utiltiies" from the menu bar and run a disc repair on your hard drive to fix any damaged OS file... then restart without the OS disc.

I receive this message when I'm booting my CISNET computer. NTLDR is compressed Press ctrl+alt+del to restart But when I do so, it comes back to the same page. Somebody please, help me!!!!!

Your system is probably trying to boot from a USB drive. ZT systems for some reason will put USB hard drives ahead of drive 0 in the boot sequence. You can correct this in the BIOS.
Another problem I had with mine is that the BIOS would not pick up the USB drives on a cold boot even though everything went fine with a restart. Cycling the power on the external after boot up solves this problem.
