Hi X and welcome to Sevenforums!

Have you tried while booting the laptop to press F8 and select "Last known good configuration"?

And if you are able to boot into Windows could you please run this and post back:

no help?

X I'm sorry that support isn't coming at the speed of light and we are a limited number of people that know how to solve BSODs. And as we here at the forum aren't really employed by M$ and help people on our freetime as much as we can, so please don't bump the thread and be patient.

Have you then perhaps tried safe boot on the computer?

 

[xornotx]

yes i have tried.

when I load cd of windows with original hard disk sata, is don t show hd for install, but I change hd sata (but fat32) windows istallation show this hd (but impossible install bevause.in fat32). Then if I connect the original HD with adapter usb, it work well on othet pc (I see all partition, system, revovery, sistem reserved).

I tried also with fix of.mbr but.nothing.

Hi,

okay well the very last thing that I come to think off is that there must be some setting inside the BIOS that makes the BSOD appear.

Usually on laptops to get into the BIOS you would have to press F2 or Delete upon booting.

What is your laptop make and model?

Cheers

Do you have your Windows 7 repair disc? With it you can try to repair Windows.

Also try to do this tutorial:

Also check your BIOS for anything with RAID controller, AHCI or IDE.

 

[xornotx]

no , sony bios is very tiny.. there is only boot option..

The BIOS from a laptop doesn't have much options.

Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely.

i can t start my notebook, bsod iastor.sys

Please try loading your BIOS for optimal default settings.

Please try loading your BIOS for optimal default settings.

I thought the iastor.sys was the driver normally associated with the Intel RAID controller found on many motherboards. And if his OS was installed with the RAID controller active make sure it is still active in BIOS. If not he could try booting with the controller in AHCI mode preferably or in IDE mode if all else fails. Otherwise we are probably looking at a corrupt driver or Hard Drive failure. No?

 

[axe0]

IRST doesn't only support RAID, RAID isn't configured on laptops.

There aren't much boot mode options in the BIOS of a laptop, I believe there are only 2 but I could be wrong as there are some laptops with quite some possibilities in the BIOS.

 

[xornotx]

no solved with default bios value

yes in notebook there was intel program https://www.sony.it/support/it/content/cnt-dwnl/prd-comp/INDOTH-00265741-0042_6260/SVT1311V2E

I ve tried also at load this driver .exe during the installation windows with my original cd for show HD at system but it don t see file .exe

 

[xornotx]

I thought of MBR rootkit or broken HD. But if the disk is broken because if I connect it to the TV is seen or if I connect it to another computer (USB adapter) I can get in all three partitions, write and read fils smoothly?

And then, if it is broken, because if you start "utility boot cd" Seagate test tool can not recognize? I have done extensive testing and ancge chkdsk thorough and there are no errors, even in smart, he says you are good.

Diagnostics Test

 Virus infection

A virus or a malware, a rootkit or a bootkit (boot sector virus) may cause such a BSOD. In this case it is needed to scan the system with a bootable virus scanner.
There are a few of such scanners available. Windows Defender Offline is a good one to do this job.

In a very little few cases it is seen that after a bootkit infection and its removal the 100 MB System Reserved Partition is converted to a logical volume. In such a case the point 6, Improper Boot Parameters

I have already done this tests. No sector corrupted, smart control is ok, chkdsk is ok, the HD is good.
