I removed the -v from the Nvram file. Left the -f booted fine afterwards. I will finish tomorrow. Thanks all for your help. Greatly appreciated.

I pressed spacebar again, -v -f was back in there. Removed and only used -f booted right up, quick. How do I permanently remove -v?

I took Herve's advice... pressed spacebar. I did see the flags -v -f I removed them, system booted into Apple logo with wheel spinning... stayed there for a very long time. Never went to login screen.

This is my org.chameleon.boot.plst Looks like GraphicsEnabler is set to YES <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>DSDT</key> <string>/Extra/dsdt.aml</string> <key>DropSSDT</key> <string>Yes</string> <key>EnableHDMIAudio</key> <string>Yes</string> <key>EthernetBuiltIn</key> <string>Yes</string> <key>Graphics Mode</key> <string>1920x1080x32</string> <key>GraphicsEnabler</key> <string>Yes</string> <key>HDAEnabler</key> <string>Yes</string> <key>Instant Menu</key> <string>Yes</string> <key>Kernel</key> <string>/Extra/mach_kernel</string> <key>Kernel Flags</key> <string>dart=0 -gux_defer_usb2</string> <key>SMBIOS</key> <string>/Extra/smbios.plist</string> <key>SkipAtiGfx</key> <string>Yes</string> <key>SkipNvidiaGfx</key> <string>Yes</string> <key>SystemType</key> <string>2</string> <key>USBBusFix</key> <string>Yes</string> <key>UseKernelCache</key> <string>Yes</string> </dict> </plist>

Here is a dumb question... how do I get to kextwizard??

It takes me to the boot loader, I press enter on my HDD to boot into Mavericks - not using -v -f It goes directly into the scrolling pages of text. Just noticed that sound is not working either. Thanks for the link to wireless cards.

I am thinking of just purchasing a usb wifi receiver - any specific model?

I was able to install Mavericks using this guide: https://osxlatitude.com/index.php?/topic/6472-dell-latitude-e7240e7440-with-mavericks-1095-updated/ Installed fine. Boots from HDD as well - only thing is that it scrolls thru about a dozen scripts before prompting login screen. Also, my wifi does not work - I have an internal Intel wifi card.

I am using the Bootpack in Post #4 https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/ Using the patched kernel Latitude_E7x40.zip 6.31MB 246 downloads

Reset BIOS, set HDD to AHCI - still won't load installer.

Tried it with GraphicsEnabler=no -x maximum=4096 same thing.

Tried -v -f -no-zp (stopped at System Uptime in nanoseconds: )

Tried it with graphicsenabler=no -x maxmem=4096 Getting the same thing...

I used Haswell 10.10.2 on usb installer. Now I can't get to the installer. I was typing graphicsenabler=no -x maxmem=4096 to load it, now this won't work. This is all I get: (This was happening before... using graphicsenabler=no -x maxmem=4096 would start installer though)

I apologize... I did type in /Volumes/"Macintosh SSD"/System/Library/Kernels/ Library had a small l in previous post... this returned no errors, brought me back to the -bash command. After I rebooted, still went into the boot loop.

Thanks for the info Jake Lo... I typed in the copy path that you posted in your previous post, cp /Volumes/"Install OS X Yosemite"/System/Library/Kernels/kernel /Volumes/"Macintosh SSD"/System/library/Kernels No errors, just brought me back to the -bash prompt. I believe that it copied it over. I rebooted - selected to boot from Macintosh SSD to finish install, Apple log flashed and went into boot loop.

I just tried typing in cd /Volumes/Install_OS_X_Yosemite/System/Library/Kernels Same error... no such file or directory. I just booted from the USB!

Typing in cp /Volumes/Install_OS_X_Yosemite/System/Library/Kernels/kernel /Volumes/Macintosh_SSD/System/library/Kernels Keep getting an error...cp /Volumes/Install_OS_X_Yosemite/System/Library/Kernels/kernel : No such file or directory I am not very familiar on how to browse directories on OSX thru terminal so I can try to view the contents of the hard drive and usb. Any Suggestions?

I redone the installer, able to install. After installation, reboots. I select Macintosh SSD to complete installation - goes back into boot loop. Any suggestions?

Actually, yes I did. Just had to unhide files.

Yes, I thought I did... checked the USB, don't see base system.dmg and base system.chunklist on the root of the USB. Going to copy and try again...

Should I wipe out the USB and start over? I used this installer guide: https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/ Tried this one first but had trouble with the DSDT.aml edit, mine showed 3 errors - steps outlined two - couldn't get the errors to go away so I could save the file. https://osxlatitude.com/index.php?/topic/6461-guide-e7440-with-clover/ which one do you suggest?

Thank you for the help. I was able to finally get to the installer. Starts to install Yosemite and then it errors "an error occurred while extracting files from the package essentials.pkg" I have ran Disk Utility and Partitioned drive, rebooted and attempted 3 times - same error. I have a Dell Latitude e7440 128GB SSD / 8GB memory / Intel integrated video card. I had to start the installer by using graphicsenabler=no -x maxmem=4096 Any suggestions on why the error on this package?

I followed the installation instructions posted here, https://osxlatitude.com/index.php?/topic/6472-dell-latitude-e7240e7440-with-mavericks-1095-updated/ Installed Bootloader for e7440. Downloaded Yosemite, boots into Chameleon and gives me the option to install - reboots, displays "invalid Partition table". I press enter and keeps going into the boot loop. Anyone have any suggestions??
