CD ROM will not boot up VISTA repair CD

August 26, 2010 at 16:33:46
Specs: Windows Vista, Core 2 Duo / 3GB
I'm upgrading a friends Sony Vaio notebook and can get the CD to boot up before the OS loads from the Hard Drive
I went into BIOS and made sure CD is set to the 1st one. Also tried it USB boot, then CD Rom, then Hard Drive.
Never wants to boot from the CD rom. Any clues.

I needed to fix the winload.exe error.
I've used Hiren's Bootable Flash Drive tool but can't find a way to launch the CD rom to access Vista Repair.

HELP!!

-Jose

Did you "press any key" when prompted? If you don't, the CD won't boot.

The Vista Loading screen never started. CD is not being accessed at all.
BIOS sequence is not following order!!

I found a another forum that someone had a similar issue.

I'm going to assume the BIOS is outdated and posibly the CD rom's firmware as well.
I just did a factory restore and will update them and see if it solve the problem for the future.

"I'm upgrading a friends Sony Vaio notebook...."

What is the notebook's model ?
The one we need to know is often shown in the bios on a Sony notebook.

If it's an old model that has a CD-Rom, only, or a CD-RW, only, drive, it can't read DVDs.

A Vista operating system disk, or a brand name supplied Vista re-installation disk, is a DVD, not a CD.
Both are compact disks, but the data on a DVD is recorded differently.

CD-Rom or similar may be listed in the bios Boot Order or similar list, but more recent notebook computers have either a CD-RW / DVD-Rom drive, or a "combo" DVD burner drive, that can read and burn both CDs and DVDs.

A "dirty" laser lens can cause the bios to not detect that a disk in the drive is bootable.
Eject the optical drive's tray, and when there is no disk on it, clean the obvious laser lens with a tissue or soft cloth.

"The Vista Loading screen never started."

You don't see the Vista loading screen right away when you actually boot from a Vista DVD. A lot of files have to be loaded from the DVD first.

"I'm going to assume the BIOS is outdated and posibly the CD rom's firmware as well."

That doesn't make any sense.

It's extremely unlikely your problems are caused by the bios version or optical drive firmware version.

If the same bios version worked fine previously, your problems were not caused by the present bios version.

You probably don't have a CD-Rom, only, drive, on this notebook, unless it's an old notebook model.

It's possible the optical drive is malfunctioning if it is supposed to be able to read DVDs, but if the firmware it has allowed the drive to work fine previously, updating the firmware is not going to help. That has nothing to do with whether the bios can boot from a bootable disk in the drive.

CD-RW / DVD-Rom drives and DVD "combo" drives that can read and burn both CDs and DVDs , have at least two lasers and associated circuits - sometimes one of those fails after the drive has been used a lot. In that case, the drive will either not be able top read any CDs, or not be able to read any DVDs.
.......

"Did you "press any key" when prompted? If you don't, the CD won't boot."

If you have the bios Boot Order or similar settings set correctly, if the laser lens is clean enough on the optical drive, if the optical drive can actually read DVDs, if there's nothing wrong with the optical drive, and if the disk is actually bootable, you will see a line similar to that on the screen while booting early in the boot sequence - you must press a key while that line is on the screen in order to boot from the bootable disk.

"I just did a factory restore and will update them and see if it solve the problem for the future"

You probably do not need to update them.

If you think the present bios settings may be out of whack, load bios defaults, Save settings, then go back into the bios and check the Boot Order or similar settings - if thats not correct, change that, Save settings.

If you change the bios version, usually flashing the bios does NOT auto load the Cmos data that goes along with the bios version - in that case, it's likely the bios will not work correctly.
To make sure the Cmos contents are matched to the bios version, you should always load bios defaults, after having flashed, and in this case, go back into the bios and check the Boot Order or similar settings - if thats not correct, change that, Save settings.
