Missing Psinfile, cannot access safe mode

Hi people

I use Windows 7 on a laptop Toshiba L730-T18R.

I have a problem with a missing psinfile, I think I deleted it so its causing a blue screen ever and Windows cannot start. I can't access Mode safe mode via F8 for a reason, its never worked. So any ideas how to proceed?

Thanks in advance.

Hello

Thank you for visiting Microsoft Community.

According to the description, I understand that your PC starts with a black screen. I will certainly help you to question.

I suggest you follow the steps mentioned below:

Method 1:

First try the Startup Repair option in the System Recovery Options dialog box. If this does not resolve the problem, or if you have additional problems manually, use the Bootrec.exe tool.

Startup Repair is a Windows Recovery tool that can fix certain system problems that might be preventing Windows to start. It scans your computer for the problem and attempt to fix it so that your computer can start correctly.

Startup Repair is a recovery tools in the System Recovery Options menu. This set of tools is on your computer's hard disk and on the Windows installation disc.

1. remove all floppy disks, CDs and DVDs from your computer and restart your computer by using the power button on the computer.

2. do one of the following:

o If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you must try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

o If your computer has multiple operating systems, use the arrow keys to select the operating system you want to repair, and then press and hold F8.

3. in the Advanced Boot Options screen, use the arrow keys to select repair your computer and press ENTER. (If your computer is not listed as an option, then your computer doesn't understand no repair preinstalled recovery options, or your network administrator has disabled the.)

4. Select a keyboard layout, and then click Next.

5. in the System Recovery Options menu, click a tool to open it.

Because you cannot start the computer, you may need to create a bootable Windows installation media, and then do an auto repair, and if this does not help then you try to restore your computer to the previous date.

Note: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

The link provided below might help you to download and create installation media.

Download Windows 7 Disk Images (ISO files)

Method 2:

Try to rebuild the BCD by using the Bootrec.exe tool.

To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

1. place the Windows 7 installation discin the disc drive, and then start the computer.

2. press a key when you are prompted. Select a language, a time, a currency, a keyboard or an input method, and then click Next.

3. click on repair your computer.

4. click on the operating system that you want to repair, and then click Next.

5. in the System Recovery Optionsdialog box, click command prompt.

6. type Bootrec.exe, and then press ENTER.

See the following link for more information:

  • Toshiba NB200 - startup problem (Windows XP) - unable to access safe mode

    Hello

    I have a laptop Toshiba NB200 with Windows XP. When I turned on, it would not start past the first screen and I couldn't make F8 safe mode.
    The only thing I can do is go into the BIOS Setup, and that's all (press F12).

    The BIOS recognizes the hard drive. Then, I created a USB stick to boot from and that made me a C: quick MSDOS having first changed the BIOS to read the USB first and also updated the BIOS (Phoenix v1.6).

    I'm not clear as to what I do then in the folder c: prompt will not let me run windows and shows just the files on the USB key.
    Should I copy the files from windows to the USB port? In addition, how will I know if the hard drive has failed and that it is unrecoverable (I hope not)?

    Any guidance welcome!
    Thank you

    Hello

    Eventually, there is no Windows OS on the HARD drive and therefore you can not start safe mode or the OS.
    You have a recovery disk or you did backup the image of Toshiba on the USB flash key?

    If this isn't the case, then you need to reinstall the OS of the own Windows XP CD.
    You could build a clean Windows XP USB flash stick that can reinstall the OS.
    I think that this should be possible since you started the laptop backpack.

    Here's a nice instruction how to do this:

  • Windows Mobile 8 slow and freezes and cannot enter safe mode

    Hi guys, I hope you can help me with a Windows laptop, 8 that gives me problems. I'm trying to help out a friend, and honestly I feel like I'm out of my depth. The initial problem was that the laptop has been slow to respond, very slow, I suspected a virus, ran a Norton scan, it turned up nothing, I ran out of time so I put in safe mode and it gives back, with a significant improvement of the laptop in safe mode. I got the laptop back today and it is always very slow to respond despite having 6 GB of RAM and specifications that must run Windows 8 very well. Is no longer possible in safe mode, and every time I try to put it in safe mode I see Start followed a white/black screen samsung, i.e. when the process ends. However when I try a normal start it starts, but at a snails pace and goes to the login screen, where it is only partially acceptable (it meets more frequently). Any help you guys can provide would be great, thanks in advance, do not hesitate to ask any questions and I'll try to get back to you as soon as POSSIBLE.

  • Cannot boot safe mode.

    Hello

    I am running Windows 7 Service Pack 1 with Suse Linux 12.2, using dual-boot.

    For some reason, I can't start mode - pressing F8 leads to a normal start with no error message.

    By pressing F12 when the Dell icon correctly, throw myself into the boot options.

    I wonder if my problem with F8 is due to dual boot or the fact that my drive is partitioned.

    Thanks in advance,

    The Dell logo is too early.  You get a GRUB prompt to select the operating system to start?  AFTER THAT is when you start, but once you see the Windows logo, it's too late.

  • Cannot boot safe mode or any mode - hangs on the mup.sys driver

    Can someone help me. I did some research on the internet and see that it is a familiar problem. I have been using a usb and someone removed without doing safely - storage key my laptop then froze and the only thing I could do was turn it off at the power button.

    Now I can't do anything - it just goes to several times on the same page saying that there was a problem to choose a way to start - I chose alone and nothing - it loads until the mup.sys driver and then just goes to the same page again. I'm out of ideas.

    Can anyone help?
    I'm trying to avoid the recovery disk that I really want to lose my job yet, but realize that might have to happen, you mind I read reports that it even still hangs when you try this option.

    Thanks Rachel

    Hello

    AFAIK the mup.sys is placed in the folder C:\Windows\System32\drivers and it s responsible for the control and the start-up of the operation of the system at the lower level (control of the printer or the graphics card, etc.).

    If your computer loads all the way up to mup.sys then your HARD drive should work. If he died it would not even charge anything at all. It would not even try to load this file.
    It is likely that this file is corrupted just.

    If you re not able to run the Win operating system and use the System Restore tool, so I put t see any other possibility to use the Toshiba Recovery CD.
    To save important files, you can remove the laptop HARD drive and connect the HARD drive to another computer via the USB interface.

  • Blue Blue screen (BSOD) / cannot run safe mode / last known configuration / normal mode

    Hello

    Depending on the subject, I tried to put it on my laptop relatively old (I use it for work only) after the shooting he goes out and were suddenly brought to the page. Now I'm stuck with BSOD and tried to fix it for the last 2 hours.

    I don't know what happened and I'm not good in it issues so I read a few posts on the BSOD issues to try to help out me, but nothing helped. By far, I tried to run the start-up test (running / hard disc as well) under the system of diagnosis and he returned with Start-up Test  Passed. I tried to run several times as suggested by some other forumers here but still does not work.

    Here are the specs / error prompts:

    Error message - BAD_POOL_CALLER

    Product number - NS136UC #ABA

    OS - WINDOWS XP

    I'd be grateful if someone would be able to help solve the problems. I have attached the BSOD page if it helps.

    TIA

    Bredd

    Hello

    Most of the time the appellant Bad Pool is the result of a damaged or defective hard drive, or it may be also that the RAM is having issues, you say you ran a test drive and it passes, so for me, it could be a case that the RAM (memory) is damaged and or has failed.  All I can say is that if you open the lower compartment of your laptop and you will find the stick/sticks of RAM (memory), if you have 2 sticks of memory remove one of your machine and see if the machine starts correctly, if not then remove the other module and re - install the module that you deleted at the beginning and see if the machine starts correctly. To remove the RAM of your machine, you will see two small metal clips on part and the other part of memory them (pushing left and right left on the right side) memory will raise slightly gently pull toward you and remove the crack, NB Please be aware that when you re-install the memory, you will notice a small notch in the RAM slot and a small cut on the cylinder itself make sure that they match before installing.  Let me know how you go...

  • Access to the Safe Mode on Windows 8

    Hello

    I understand sometimes through troubleshooting or for other reasons, there is a need to access safe mode when using windows 8. What many people do not know is Windows 8 does not use F8 at startup to access the secure mode. It needs to be done inside of Windows 8, himself. The screenshots below will show you how to access safe mode when you use Windows 8.

    On the startup screen, click settings:

    Then click on change settings for PC:

    Click gernal on the left side of the page:

    On the right side scroll advanced boot:

    The computer then stops, and you want to click on troubleshoot:

    Click on advanced options:

    Click startup parameters:

    You will then see a page that lists information, click Restart on the right:

    You will then choose which environment you want to connect to:

    I hope this information is useful
