HT3986 Soundless after installing Win7...

I have installed Window7 in my iMac.
However it became soundless in Window side but normal in Mac OS...
I'm now using Mac OS X 10.5.8.
Could anyone help please? Thanks lot!

I have exactly the same problem on my iMax too. It says all drivers are installed and it would appear to indicate no problems... but still no sound. Even if I plug speakers into the headphone jack, nothing.... most annoying!
Any ideas?

After installed win7 on my mac pro(mid 2012/mountain lion), I can not connect internet and where can i find drivers in mountain lion system.
I donot think I have a install disk when I bought my mac, there is only a disc partition for recovery system.

Welcome to the Apple Support Communities
You have to install Boot Camp drivers. On Mountain Lion, you have to download them.
First, press X key while your Mac is starting to start into OS X. Then, open Boot Camp Assistant and select the option to download the drivers. You will have to burn them into a DVD or USB drive, so after downloading them, restart and install them into Windows

Hi Jim,
You're welcome
Is the version of Windows 7 Ultimate you have installed 32bit or 64bit?
Open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers - do you see an existing entry for the IDT High Definition Audio CODEC listed here?
There is an alternative IDT Audio driver you may wish to try on the following link.

Let me know if you get the same error with this version.

HT1338 Can't access my mac os side after installing win7

I just installed windows 7 on my new mac using boot camp. I followed all the steps but after installing win7 there is no way I can access my mac os partition. I tried to reboot with the Alt/option key pressed but I am presented with a window asking me to provide a password. When I enter my password, it won't let me in. It just delete the password. I have re-tried several times but it won't work. My question are:
1. Is there any way I can install windows support software (for the driver) from bootcamp since I cannot access my mac side.
2. I tried to download and install bootcamp but it doesn't work since it says I do not need to install any bootcamp update.
3. Is there any ways I can go past the mac password screen? I really don't understand why it doesn't accept my password. I am the only administrator and user of my computer

#3. Try things in this Reset Password faq.

After installing Win7, I created an 3a. partition and now I can't boot with Win7

After installing Win7 with success, I created an other data partition and now I can't boot with Win7 anymore. What can I do?
Thanks!

Thanks, hatter! But I´m new in the Mac World and that´s greek for me. I have no idea about what is BCDedit, GPT, EFI, etc... I went to your bookmarks and found many discursions there. I selected 5 that the subject looks useful for me (https://discussions.apple.com/thread/3543804, https://discussions.apple.com/thread/3477901,
https://discussions.apple.com/thread/3360787, https://discussions.apple.com/thread/3354587 and https://discussions.apple.com/thread/3199099) but, as a tipical windows user, a really new mac user and a non-american (I don´t speak English well), it´s impossible to me to understand all this.
Do you know any "how to" in this forum or i any other part of the Internet where explain step-by-step what a dummy needs to do to recover the acess to the Windows partition (my primary objective) and create an third partition (FAT32) for data acessible for both OS?
Thank you very much!

HDX18t unrecognized devices after installing Win7

After a clean install of Windows 7 Ultimate, Device Manager reports three Base System Devices without drivers and two Unknown Devices (ACPI\ENE0100 *ENE0100) and (USB\VID_138A&PID_0001&REV_0372 USB\VID_138A&PID_0001).
As far as I can tell, all the USB ports work correctly, as does everything else I have tested (some ports I don't use). I presume ACPI has something to do with power management, but I can't find any other indications of power problems -- although I had to replace the battery not long before installing Win7 because it wasn't charging.
What are these five devices, and how can I find drivers -- especially for the three that don't seem to identify themselves?
I tried to use the "automatically find your products and solutions" tool, but it won't load into the latest version of SeaMonkey, and with IE9 it appears to start but shows zero progress after more than an hour.
Any suggestions?

Still restarts after instalation WIN7

Hi everyone,
I have problem, I have bought Lenovo IdeaPad G570 without OS. I tried to instal WIN7, everything going fine, but at the end of instalation, notebook wrote "logon process initialization failure" and still restarts. In instalacion I deleted partitions, and format the new one so i havent my backup file. I tried to recover it, but still the same. Could you help me pls.

System get restarted after installation of windows. I would suggest you to kindly check the SATA mode controller in the BIOS mode, change it to IDE or compatible mode. To do so please restart the system and press F2 key continuously, Bios screen will appear.
Also you can check with other operating system.
Thanks & Regards,
Sameer

Satellite A300 (PSAG8E) - Hardware problems after installing win7 ultimate

Hello and good day,
I've installed win7 ultimate a few days ago and windows managed to recognize most of my hardware accept my build in mic and camera and another component I am not sure about what it is (Windows update automatically downloaded the sound and graphics driver for me).
My questions are - where can find the remaining drivers and where can I get the preinstalled Toshiba tools and software? (The driver site in the Toshiba support page does not include those drivers and software)
Thank you very much
Roi Ben Simon

Hi
I have Satellite A300 (PSAG8E) too and installed Win7 Home premium and everything works perfect.
At first I must say that I don't know where you have searched drivers and Toshiba tools and utilities because all stuff is downloadable on Toshiba support & download page under http://eu.computers.toshiba-europe.com
It is logic that mic will not work if you didn't installed proper driver. Install drivers alone and not using Microsoft update. What you need are real and tested drivers and not some free drivers from internet.
Go to Toshiba download page and install all stuff following this installations order:
-Win7
-chipset driver
-storage manager
-display driver
-sound driver
-modem driver
-supervisor utility
-infrared
-patches
-configfree
-VAP
-toshiba hardware setup
-HDMI control
-WLAN driver
Everything works well but missing some drivers
Added Vista stuff:
-Toshiba assist - work properly
-Card reader - installed properly
-Webcam driver for A500 - tested with Skype - work properly.
-Synaptics driver

After installing Win7 x32 SP1 I can not start Firefox. Not even in safe mode. I uninstalled Firefox and re-installed the program. Won't start.

After installing SP1 Firefox quit working and Internet Explore quit working. I can only use Chrome as a browser at this time.

See:
*http://kb.mozillazine.org/Browser_will_not_start_up
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

After installing win7 in bootcamp mac mini start only in windows

I did install win 7 Home edition premium on my mac mini the same way as I did on my iMac.
After the install I could booth Win7 but there was no bootcamp icon and it would always boot in win7.
No way to go back to Mac OS whatever key press I tried. And there was no bootcamp.exe.
As I am unning Lion and there i no DVD I installed bootcamp in Windows using the leopard DVD.
After restart it came back to Win7 and now the bootcamp icon was there. THrough teh bootcamp
icon i was able to restart in Mac OSX. From there I checked the harddrive and no error was reported.
I then when to bootcamp and set it to restart in Mac OSX. It did restart but didn't boot at all. Just get
the beep and that's it.
Nothing helps: option, D, Shift, P&R,...
I had a problem before that the Mac Mini would shutdown with no reason and no warning at random
times. I brought it to the Apple store and they allegedly repaired it. Could this be related?
I have other Mac mini (Intel) older and also the previous version with the DVD as well as a Mac Book Pro
and an iMac with excatly the same configuration and never had any problem.
I need help thanks,

yes, no luck there either.
Now I cannot boot at all.

Missing drivers after installing Win7

Hallo
On my just new macbookpro, i installed an original Win7 home premium 32bit.
All seemed to go right, Windows is working ok, but most drivers are missing!
How to pick them up from internet if you cant't be connected to??
Where can i find them (the right ones)
thanks

Below is reproduced a procedure the BC Install Manual suggests.The Windows install DVD can do the same sort of thing if it is the Windows drivers that are missing.
You can find the entire PDF document here:
http://manuals.info.apple.com/enUS/Boot_Camp_Install-Setup10.6.pdf
If You Have Problems Installing the Device Drivers
If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
To repair Boot Camp drivers:
1 Start up your computer in Windows.
2 Insert your Mac OS X installation disc.
3 If the installer doesn’t start automatically, browse the disc using Windows Explorer and double-click the setup.exe file in the Boot Camp directory.
4 Click Repair and follow the onscreen instructions. If a message appears that says the software you’re installing has not passed Windows
Logo testing, click Continue Anyway.
If you need to reinstall specific drivers, you can install one driver at a time. For example, if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
Individual drivers are in the Drivers folder on the Mac OS X installation disc.
To reinstall a specific driver:
1 Insert your Mac OS X installation disc. 2 Quit AutoRun if it opens. 3 Using Windows Explorer, locate the driver that you want to reinstall. 4 Open the driver to start the installation.

Unable To Write Right To Left (After Installing Win7 SP1)

Hey You All!
Yesterdy I've Installed Windows 7 Sp1,
And Today When I Tried Writing In Hebrew (Right To Left)
In My Photoshop CS5 - ME (Supports TRL Writing), It Writes Backwards
Like If I Were Using Regular Non Hebrew/Arabic Supporte Text...
Has Anyone Else Encountered This Problem? Please Help, It's Slows Me Down In My Workplace!!!
Thanks!

Hey Again!
Well First Of All Thank You For Trying And Helping Me!
I've Tried To Look For A Sloution But With No Luck, But...
It's Seems That There Is Something Even More Weird Going On,
As You May Know Once You Install Photoshop CS5 (ME Or Not) On A Win7 64Bit OS
It Installs Both 32Bit And The 64Bit Versions... So Here's The Weird Part:
1. If I'm Typing In Hebew In Ther 64Bit Version - You Get The Letters Backwards
2. But If I Use The 32Bit, Evertyhing Seems To Be Working Okay...
What Do You Think Is Going On?
I Also Failed To Mention That I Also Updated To IE9 Perhaps It Is Causing The Problem Also?
Anyone?

G400s after installing win7 problems..

I install windows 7 in this preinstalled windows 8 notebook, but there're several problems that I need helps with.
1. After installation, the preinstalled programs like youcam and onekey recovery are gone. I can't find them in the g400s drivers download page.
Please let me know where I can download them, and what other preinstall programs beside youcam and onekey, that are useful and I might want to install.
2. So if onekey recovery doesn't work in windows 7, what should I do if I decided to change back to windows 8?
I don't have product key or cd since it's already in the system when I bought it.
3. After installation, my 2nd hard disk (named Lenovo something), just disappeared.. and now left with just 1 disk.
What happened?
Please help! Thanks!

One Key Recovery (OKR) works with Windows 8 pre installed OS using a special partition that is on the hard disk drive. When you installed Windows 7 it mostlikely formatted the entire drive, wiping out both the Windows 8 partition and the OKR partition in the process.
At this point the Windows 8 files are lost and if you wish to re-install Windows 8 it will require the recovery disk set purchased from Lenovo Support. The other programs that were loaded on with the orginal disk may not be supported by Windows 7, or there are no drivers in Windows 7 to support the hardware that is linked to that software.
Good luck.
