I'll try to keep this reasonably concise.I have a system based on an Asus P6T Deluxe (X58, BIOS 1611, Core I7 920 CPU, 12 GB of DDR3 RAM) mainboard. I'm running the 90 dayeval version of Win7 Enterprise X64, with a Crucial CT128M225 SSD (SATA, Indilink controller)as the boot drive. The SSD has firmware 1571. I tested with a clean install of Win7. (I deleted the partition from the SSD, re-created it, and formatted the primary partition.) I'm using 3 HDs and two optical drives, all on the Intel SATA controller. For the test, I did not install the Intel chipset drivers. (I had the problem earlier with the drivers installed, though.)Otherwise, I have an nVidia GTX280 graphics card, two USB printers, and USB keyboard and mouse.The system boots nicely into Win7. The odd thing is that I can't boot into Safe Mode. If I try it, it proceeds as far as the "Welcome to Windows" screen. Then the USB controller seems to quit (light on my USB mouse goes out), then the display goes black. (No bluescreen was visible, even momentarily.) The system then proceeds to reboot. (I have reboot on error turned off in Windows. There's no effect here.) I have never seen a system before that could boot into Windows, but not Safe Mode.I get the same thing whether I am running the SSDin IDE or AHCI mode. I normally run with an overclock, but returning to stock makes no difference.I have not tried to change any settings to optimize the SSD.Nothing is written to the event log, other than an error that theprevious shutdown wasn't normal.A bit of quick Web searching hasn't found anything suggestive.I like the SSD, but I'll be disappointed if it breaks the ability to boot into Safe Mode. The problem didn't exist while I was using a Velociraptor 300 as the boot drive.Have others seen this problem?

Sacre merde!8 hours, and not a single response.Must be an obscure problem. Just my luck.

This may be a bug of sorts for the build you are using 7 Enterprise 90 day Evaluation and another poster reported it here:http://social.technet.microsoft.com/Forums/en-US/w7itproperf/thread/ef0e41cb-955b-4a29-9318-2c56a198d746Boot back to normal mode and try again.

Thanks for the suggestion.I reverted to the RTM build. The system now cheerfully boots into safe mode.I wonder how common the problem is with the Enterprise X64eval version? I hope that there is no large number of people who find out that they are affected when they need safe mode for maintenance.(How different are the RTM and Enterprise Evaluation versions? The E. E. iso is approx. 100MB smaller than the RTM one.)

One thing I discovered, safe mode with networking, no problem. Safe mode minimal, it restarts.
