HYPer-v 2012 R2 NIC team breadown after Broadcom Driver upgradation

Hi Team ,
I am using Blade server with Two Broadcom BCM57800 NetXtream 10 G ports . Both Network card configured in one team with Switch independent and Hyper-v Port configuration using Windows Native teaming.
I upgraded the firmware driver of network card to the latest level and then after Hyper-v Team stop responding.
i am using Single virtual Switch with one vNIC so hyper-v can talk to mgmt LAN on Vlan X.
as an work around i break the team and configure one nic for Mgmt IP and other for VDItraffic (Virtual Switch)
please let me know if any one face similar issue and able to resolved it.
Thanks
Ravi

Server 2012 R2 Network Teaming Issues After Adding WOW64 Feature

Recently I have had a specific issue adding the WOW64 feature to an active Server 2012 R2 server in core mode (no management). The server had two active virtual machines. A server 2008 R2 in version 1 mode and a 2012 R2 in version 2.
All were up2date as of April 10 2015. This was a domain connected core with domain connected virtual machines. We are the domain administrator.
After using powershell to install WOW64 and issuing a restart we lost all external network connectivity to the server once the server came back up. From the console we could ping 127.0.0.1 and all the network addresses of each VM but not the
default gateway or any address on the local network. We tried several resolutions including disabling all firewall rules and assigning a known VLAN but nothing worked. Something went completely haywire within Windows 2012 R2 and network teaming
and the virtual switch that supplies the VM's with communication.
What we had to do was remove one of the physical network adapters from the team using powershell from the core console. We then assigned an address to the nic and whallah we were able to remotely communicate to the server again but the problem
still remained with communicating to the team.
After hours of trials we finally stumbled on a solution deleting the hyper-v virtual switch though a remote console, then the team through powershell. This of course broke all the hyper-v VM's. We said f'it and rebooted.
This is the magical combination apparently
We then recreated the team using the remote management GRAPHICAL widget using every physical EXCEPT the nic we were communicating to.   Then we recreated the hyper-v virtual switch remotely again with the GRAPHICAL widget and assigned
it an address using the command line sconfig tool.   We then went into the GRAPHICAL hyper-v manager and assigned all VM's to the new virtual switch. WOW everything works again
Let me just say here in this post that the lack of graphical management in CORE mode is a complete nightmare. The fact we have to use some graphical tools to perform certain tasks and the command line for others is just silly. The sconfig.exe
tool should have built-in teaming commands as inexperienced remote administrators are very difficult to work with over the phone trying to explain spelling of the upper/lowercase commands.
This post is more informative than really asking a specific question but if I were to ask one I'd ask, why did installing the WOW64 feature and rebooting break the external communication of the team and the virtual switch?

Hi gettnmorebetter,
Could you try to confirm whether you have in the following situation, if you do not found the related symptom please try to install the latest update then monitor the issue
again.

Windows Server 2012/2012R2 NIC Teaming Mode

Hi,
Question 1:
In Windows Server 2012 the following teaming mode was recommended for Hyper-V NIC teams:
Teaming mode: Switch Independent
Load balancing mode: Hyper-V Port
All Adapers Active
In a session at TechEd 2014 it was stated that Dynamic is the new recommendation for Windows Server 2012 R2. However, a Microsoft PFE stated a few weeks ago that he would still recommend Hyper-V Port for Windows Server 2012 R2. What is your opinions around
this?
Question 2:
We have a Hyper-V Failover Cluster which isn`t migrated to 2012 R2 yet, it`s running 2012. In this cluster we use Switch Independent/Hyper-V Port for the team. We also use converged networking, having 2 physical adapters bound to the NIC team, as well as
3 virtual adapters in the management OS for management, CSV and Live Migration. Recently one of the team NICs failed, and this incident also caused the cluster membership on the affected node to go offline even though the other team NIC was
connected. Is this expected behaviour? Would the behaviour be different if 2012 R2 with Dynamic mode was being used?

Hello,
As for question number 1:
For Hyper-V workload it's recommended to use Dynamic with
Switch Independent mode. Why?
This configuration will distribute the load based on the TCP Ports address hash as modified by the Dynamic load balancing algorithm. The Dynamic load balancing algorithm will redistribute flows to optimize team member bandwidth utilization so individual
flow transmissions may move from one active team member to another. The algorithm takes into account the small possibility that redistributing traffic could cause out-of-order delivery of packets so it takes steps to minimize that possibility.
The receive side, however, will look identical to Hyper-V Port distribution. Each Hyper-V switch port’s traffic, whether bound for a virtual NIC in a VM (vmNIC) or a virtual NIC in the host (vNIC), will see all its inbound traffic arriving on a single
NIC.
This mode is best used for teaming in both native and Hyper-V environments except when:
1) Teaming is being performed in a VM,
2) Switch dependent teaming (e.g., LACP) is required by policy, or
3) Operation of a two-member Active/Standby team is required by policy.
As for question number 2:
The Switch Independent/Hyper-V Port will send packets using all active team members distributing the load based on the Hyper-V switch port number. Each Hyper-V port will be bandwidth limited to not more than one team member’s bandwidth because the port
is affinitized to exactly one team member at any point in time.
In all cases where this configuration was recommended back in Windows Server 2012 the new configuration in 2012 R2, Switch Independent/Dynamic, will provide better performance.
Microsoft recommend for a clustered Hyper-V deployment
in Windows server 2012 to use Switch Independent/Hyper-V Port as you mentioned and to configure
Hyper-V QoS that applies to the virtual switch. (Configure minimum bandwidth in
weight mode instead of in bits per second and Enable and configure QoS
for all virtual network adapters
Did you apply QoS on the Converged vSwitch after you
created the team?? However Nodes are considered down if they do not respond to 5 heartbeats. The Switch Independent/Hyper-V Port does not cause the cluster to goes down if one NIC failed. The issue is somewhere else and not in the teaming mode
that you choose.
Hope this help.

2012 R2 NIC Teaming and netwroking

I have a 4 port NIC, all connected to the same network using DHCP, when I team two cards, they no longer have an IP address. Is that by design?
Where can I find more information about the virtual networking how to?
TIA

Yes it is by design.
If individual NICs are configured with IP settings and then you create a NIC teaming the individual nics will lose their IP settings.
And you will no longer be able to configure the ip settings on the individual NICs which are part of a NIC team. Instead you will need to assign the ip address on the NIC Team.
To assign ip address to the NIC teams, go to control Panel\ Network and Internet\ Network Connections
To assign VLANs and manage/update Team interfaces: In the Server Manager select the local server and then in the local server properties section click on Nic Teaming "Enabled" link.
This will open the NIC teaming window and here you can manage the NIC teams.

Windows Server 2012 R2 NIC Teaming and DHCP Issue

Came across a weird issue today during a server deployment. I was doing a physical server deployment and got Windows installed and was getting ready to connect it to our network. Before connecting the Ethernet cables to the network adapters, I created a
NIC Team using Windows Server 2012 R2 built-in software with a static IP address (we'll say its 192.168.1.56). Once I plugged in the Ethernet cables, I got network access but was unable to join our domain. At this time, I deleted the NIC team and the two network
adapters got their own IP addresses issued from DHCP (192.168.1.57 and 192.168.1.58) and at this point I was able to join our domain. I recreated the NIC team and set a new static IP (192.168.1.57) and everything was working great as intended.
My issue is when I went into DHCP I noticed a random entry that was using the IP address I used for the first NIC teaming attempt (192.168.1.56), before I joined it to the domain. I call this a random entry because it is using the last 8 characters of the
MAC address as the hostname instead of the servers hostname.
It seems when I deleted the first NIC team I created (192.168.1.56), a random MAC address Server 2012 R2 generated for the team has remained embedded in the system. The IP address is still pingable even though an ipconfig /all shows the current NIC team
with the IP 192.168.1.57. There is no IP address of 192.168.1.56 configured on the current server and I have static IPs set yet it is still pingable and registering with DHCP.
I know this is slightly confusing but I am hoping someone else has encountered this issue and may be able to tell me how to fix this. Simply deleting the DHCP entry does not do the trick, it comes back.

Hi,
Please confirm you have choose the right NIC team type, If you’ve previously configured NIC teaming, you’re aware NIC teams usually require the assistance of network-side
protocols. Prior to Windows 2012, using a NIC team on a server also meant enabling protocols like EtherChannel or LACP (also known as 802.1ax or 802.3ad) on network ports.

Server 2012 R2 NIC Teams

Hey guys, i was hoping someone could help me understand this. I kind of get how this teaming stuff works, but i want to make sure I'm not doing anything wrong/ not supported.
So for the past few days I've been trying to wrap my head around this stuff. And this is what I have so far.
R720 Dell Server --> 4 Teamed NICs ---> Multiplexor --> vSwitch --> VMs
So the vSwitch is connected to the multiplexor and the VMs are connected to that switch. I figured I'd try to see if i saw any performance differences. As a matter of fact I saw it got worse. Sometimes the VM on the server stays connected, other times it
gets disconnected and wont reconnect
When I do a LAN speed test to another server i get like 9 Mbps vs other servers that are connected strait from a nic to a switch and that switch to a server that gets 800 Mbps +
I did a switch independent with dynamic LB. I did some looking up on all of the settings, but I really dont understand why its so slow.
Also if i were to create vNICs based off that switch for lets say, management, cluster, live migration etc..
So, the NICs are based off that vSwitch and you can do the Qos for those NICs, but I'm confused as to how those NICs are specifically used.
If none of that made sense, i'll be around looking for some more info and i can elaborate if need be.

Hi,
In switch
independent mode, outbound traffic bandwidth could be increased. If you want improve both inbound and outbound bandwidth you could configure a switch dependent
mode. And it is recommended to choose hyper-v switch port as
Traffic distribution algorithms.
For dynamic teaming
most switches require manual administration to enable LACP on the port.
At last, you referred that VM lose connection intermittently. I wonder the VM lose connection with your virtual switch or lose connection with the other servers.

How do I reinstall my operating system after hard drive upgrade on MacBook pro? I have Snow Leopard install disc

How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
HELP PLEASE!!

Is the new HHD in the MBP?
Is the new HDD formatted Mac OS Extended (Journaled)?
Where is the old HDD? In an enclosure? What is on the old HDD, your user data? Is the Snow Leopard System on it?
Do you have a separate Time Machine Disk with your user data?
Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.
Ciao.

Spinning beach ball after hard drive upgrade

Im running a macbook pro i7 2.2ghz 8gb ram version 10.6.8 SL
I recently upgraded my 128gb ssd to a 512gb ssd drive. I cloned the drive to new drive and ever since then, I get the spinning beach ball very often whereas I never got it prior to the hard drive upgrade. Is there anything I can check or do to eliminate the freeze ups? It is VERY annoying. Or do I just need to do a fresh install on the new hard drive.
thanks in advance

Did you properly prep the drive first:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

MBP mid-2009 Freezing after Hard Drive upgrade -HELP!

So, my Apple Care just ended and I was almost always at a full 320GB, so I decided to upgrade my hard drive to 1TB. I purchased a Western Digital TB drive (9.5mm) at a store recommended by an Apple Genius and followed the instruction on youtube exactly, as well as having another visit to the Genius bar, ensuring I grounded myself often throughout the process. My computer is a 15" MBP originally loaded with Snow Leopard, now running OSX Lion. I did a Time Machine backup prior to everything and also bought an enclosure for my old hard disk to use and it has yet to be wiped, but Disk Utility says that it's corrupt because 1 program's debug log says the number of files changed (after the time machine processing.) I did a Carbon Copy Clone prior to installing the hard drive as well, so when all was done, I was able to start the computer without issue. (This program is what told me first that I had an issue with that debug log. I'd tried to delete a huge folder that was taking up nearly 30GB before the clone, it was backed up on time machine and another backup drive.)
However, after Vuze re-opened (which I'd just recently upgraded to Pro) it froze the computer, so I got the rainbow disk and even Force Quit did not work. Since then, I've had to reboot with the top right button dozens of times. Mail, Chrome and Vuze have all caused freezing and Command Option Escape does not work at all. My beloved computer is starting to feel like a big brick. I uninstalled and re-installed Vuze Plus since, but still have the same issues (trashing the program then re-downloading). As for Disk Utility, it says the drive is just fine. There are no software updates needed and that's about as far as I can get before things crash again.
I would really appreciate any assistance that can be provided based on this scenario. I hope I've provided enough detail, please let me know if more is needed.
Thank you in advance.

The only thing that I can think of is that your SATA cable may be bad... it's the first thing that I would try replacing. DIsk Utility wouldn't be able to detect a bad SATA cable - you'd just have random freezes and crashes.
I don't know that this is the solution to your problem, but it's the first thing I would attempt. 2009 models are notorious for having bad SATA cables - try PowerbookMedic and order a new one. If it doesn't fix the problem, call back.
Good luck,
Clinton

Hard drive will not mount after optical drive upgrade

I recently performed an optical drive install. Had to remove the hard drive bays (I use three hard drives - Luckily, 2 run OSX).
I carefully removed all three drive bays and the empty bay. When I inserted the drives into the computer I had changed the position, swapping one OSX drive with a different one and reversing the drive bays. On restart, the computer started on the drive I had not selected for startup and I received an error message stating the other drive could not mount and it gave three options (Initialize - Ignore and Eject).
I can see the drive in Disk Utility and repair the permissions (it's also located in the System Profile).
I tried a few things I read in the community using various Terminal commands but was unsuccessful.
(Let me point out that I recently switched from a PPC G5 to MacPro and swapped the drives from PPC into MacPro and all has been fine until I removed changed their positions in the bays)
Any suggestions/help would be greatly appreciated.

I would recommend you reformat your drives that you brought over, and if possible put in a Firewie case.
Swapping drives will normally not matter but you should use Startup Disk to reset the default after using Option key the first time.
Putting in an optical device shouldn't require removing the drives to get the cage loose and let you put in a 2nd superdirve.
G5 used APM partition map, Intel Macs use EFI and requie GPT/GUID.
A drive with just data should not matter but that is not fool-proof either.
A drive iwth the system from a G5 though can.
During startup the boot process scans all volumes and looks for systems and mountable volumes.
Pull all the drives except the one with OS X that you were using, and put that in bay #1.
I've moved arrays between bays and that never "broke" the array or had trouble mounting and using (even moving to ODD ports).

How do you install OS after Hard Drive upgrade? Thinkpad T41p

I have a Thinkpad T41p with Window XP Pro on it. I have a new larger hard drive for it, but I do not know how I will be able to install the OS on the new drive. The laptop came with the OS already installed on it. That will to be the case, of course, for the new hard drive. So what do I do? If you could point me to a step-by-step procedure, I would be most grateful. I have installed numerous OSs, so I am familiar with how to do that from installation CDs.
Thanks in advance for the help.
GKent

Just went through this process on my wife's T41. I did the following:
downloaded and installed the eval copy of Active@ Disk Image and Active@ Boot Disk (created a boot CD).
rebooted to the BIOS setup and in the security setting for the IBM Predesktop Area I selected Disable saved the changes and booted
rebooted to windows and usedActive@ Disk Image to create a raw image of the entire disk to a USB hard drive
Shut down and removed the original hard drive and installed the new empty hard drive
rebooted using the CD created by Active@ Book Disk and started the Active@ Disk Image utility
selected the Image to Disk option. This took the raw image and installed it on the new hard drive (this included the hidden partition as well as the windows partition
rebooted without the boot cd and logged in to windows
rebooted into the BIOS and reset the security setting for the IBM Predesktop Area to Normal, saved changes and booted
result is the same size partitions as before on the new 80 GB hard drive so I then ran Partition Magic to resize the Windows partition to utilize all of the remaining space on the disk (left the hidden partion in place - it is still bootable)
rebooted and I now have a 74.5 GB drive for windows with all of the installed software intact
I did plan on using the recovery option to reinstall the image to the factory settings since I had a few issues with windows on the original drive. Ran Rescue and Recovery and it could not find the restore images After much searching it appears that I will have to go out and buy the CDs (unless someone has a free download option)

MAC OS 10.4 CRASHES AFTER HARD DRIVE UPGRADE

I just bought a HITACHI hard drive for my iBook G4 1.33ghz. I installed the hard drive with no problems. After installing MAC OS X 10.4.2 & upgrading to 10.4.11, the OS keeps crashing, Ive done a APPLE HARDWARE TEST everything fine, Ive used disk utility to check for problems everything fine, Ive contacted HITACHI not response (3 week have past by). Im runing out of ideas. HELP!

Hi,
You say
while OSX can easily be installed and booted from an external HD,
Stefan
Well I thought it should be easy, but I must be missing something. I bought a 100GB HD for a laptop that didn't turn out to need it, so I thought it would be good to install 10.4.11 on it so I could use it to start up coomputers having HD problems. I put it into a USB "slim carrier", plugged it into my iBook, put the install disk into the superdrive and clicked install. When the iBook re-started and the installation steps showed up, the drive showed up, but the install program showed the drive as a non-installable location.
Is there another way to do this? Must it be in a firewire enclosure, or should USB work?
Many thanks for any hints here,
...Tom

Lost Printer Sharing after HP Driver Upgrade.

I have a 3.06 Intel Core Duo iMac and a 253 Intel Core i5 Macbook Pro. Both are running 10.6.8. They have until recently successfully shared my HP C8180 All in One Printer, the iMac being connected to the printer via USB and to a Netgear Router via Ethernet and the Macbook Pro being linked to the router wirelessly.
Having just updated the HP Drivers via software update on both machines the Macbook Pro is no longer able to connect to the printer via the iMac wirelessly and the printer is not reported as being "Nearby". It does however connect via the iMac if it is connected to the router via Ethernet !
Printer sharing is on on the iMac, I have tried removing the printer from both machines Preferences and re-instating them (which coincidentally has meant I have lost the connection to "Lightscribe" and can't get it back on either machine !) I've tried installing the latest HP Software to try and get the Macbook pro to connect to the printer directly via the router but witth no success - it reports that some of the HP software is not compatible with 10.6.8 despite HP saying it is for 10.6.
Does anyone have any idea how I can get the laptop to print in the way it did up until earlier today and how to get "lightscribe" back?

After more experimentation I found that not only was Printer Sharing not working neither was File Sharing but printer sharing worked if both computers were connected to my Netgear router by ethernet but not when the laptop was connected wirelessly.
This suggested a wireless problem, possibly within the Netgear Router. As both could access the internet however they were connected to the router it looked as though the router was not passing an incoming wireless message from the laptop out to the iMac via ethernet.
I finally found a solution to the printer sharing part of my problem. I remembered eventually that I had a similar problem some many months ago and that it resolved itself after all of my equipment had been switched off and disconnected from the mains power.
Consequently I switched everything off, unplugged it all from the mains power supply and left it for 25 minutes. On reconnecting and rebooting everything the printer sharing now works properly again with the MacBook Pro connected wirelessly and the iMac via ethernet to the router an, for printing, the iMac via USB to the printer.
I think that the loss of "Lightscribe" may relate to the way the printer is set up internally. Reviwing the Printer User Manual I suspect that it is probably reverted to a set up allowing control of "Lightscribe" internally rather than via a computer (possibly this happened after a reset of the printer to factory settings some time in the past) and when I removed Lightscribe from the list of printers in the iMac's Print & Fax preferences the iMac couldn't find it again. As I don't use "Lightscribe" I'm leaving well alone.
Hope this self reply helps others.

Fans are running at full speed after hard drive upgrade. Used same brand drive.

My Western Digital 500GB hard drive crashed. The date on it is Aug. 2010. I swapped it out for a Western Digital Caviar Black 1TB. All plugs were identical including the temp sensor cable. My fans now run at full speed. What gives? BTW. This is th 3rd WD hard drive to fail at my office in multiple iMacs. I have a 21.5 iMac i3 3.06ghz. I have tried the SMC reset,.. no luck. Reset the PRAM,.. no luck. Hard drive and computer function perfectly, it just sounds like a loud annoying PC.

After a little more research the only thing I found for 21.5" mid 2010 imac were three part numbers for three sensor cables which are a function of vendor:
922-9215, Hitachi
922-9216, Seagate
922-9622, Western Digital
The strange thing here is these are vendor specific and not model within vendor specific. So you started with a WD drive and replaced it with different model, but still a WD drive. So you would think it would require the same sensor cable.
Maybe the drives are different enough for this to matter. Or maybe you should check the connections one more time. Be it model of drive or connections, whichever it is, the sensor cable is the source of your problem.

Do I have to re-do BootCamp after hard drive upgrade?

I currently have an early-2011 MacBook Pro with 500GB storage. I ran BootCamp and now have a partitioned hd with 300GB on my OSX side and 200GB on my Windows side. I'm running out of space and want to upgrade my hd to a 1TB hd and was wondering if the ratio of storage space would be the same after the upgrade or if I would have to re-do BootCamp and re-install Windows. I have been backing up my computer on an external hd and would be able to go back to the way it was before I ran partitioned it, and since only games are on the Windows side (mostly through Steam), it wouldn't be too hard to start from scratch and re-install the games. So basically this is what I'm asking: after upgrading my hd from 500GB to 1TB, will I have to do BootCamp all over again or will I be able to choose how much space I put on each side of the partition?

There is a surprising amount of misinformation about this topic. I don't know whether the people who make Winclone are to blame, but if you look right across the internet you'd be forgiven for coming to the conclusion that the only way to move, restore or resize your bootcamp petition is to use paid software. This is simply not true. If you're willing to spend some time and follow a couple more steps, it's easy to install a new hard drive, and put both your OSX and WIN7 partitions back precisely as they were (or resize as you please) without using anything other than freely available utilities.
The way I've come up with uses a 160GB Maxtor USB drive and a DMG image of your bootcamp partition stored on a networked computer. I intended to write these up with screenshots at some point. But for now here are my unedited notes.
1 - use a utility called SuperDuper to create a bootable exact copy of your OSX partition - this is where the Maxtor external drive was used. One of the beauties of Apple OS - you can boot from a portable drive...
2 - Use the Disk Utility (Applications - Utilities) to create a DMG of your bootcamp partition - move this to a networked computer
3 - Create a bootable CD of the partition management program "GParted" by downloading and burning an ISO from their website.
Next step depends on what you want to achieve - this assumes you're installing a new drive.
4 - Install your new hard drive - plenty of videos around on how to do this, not hard.
5 - Plug in the drive that you used to create a backup of the MAC OS and hold down option when turning on - boot from the external drive
6 - Using the disk utility, create two partitions on your brnad new internal HD. Size doesn't really matter at this stage - just so long as one is big enough to fit the MAC OS
7 - Using SuperDuper copy your MAC OS back onto the first of the new partitions
8 - Before you restart, restore the DMG image you've stored on a networked computer (Images-scan for restore) to the second partition. It's important that you are still running off the external drive when you do this as otherwise you'll get a "resource busy" error when you try to restore.
9 - Shutdown. Turn on holding down option. Fire up the GParted disk you made early. It's an ugly interface, but gets the job done. Just accept the default settings when asked questions when starting up.
10 - Using Gparted delete any extra partitions that have may have crept in (I had a FAT32 200MB partition that was causing issues) - what you should have is only two partitions the HFS and the NTFS partitions. You can resize these to whatever you feel like. This may take some time. Moving partitions around on a 750GB new drive took about 4 hours. Shutdown and unplug everything.
11 - Turn on and hold option. Select the Mac OS hard drive and your OSX will start. At this stage you won't be able to boot into Windows - that comes in a moment.
12 - Download and install ReFit. Go into system preferences-startup disk and and make sure that the Mac OS is selected. Restart twice. Twice is important - that's when you should be greeted with the ReFit screen when you restart the second time.
13 - On the refit menu, select the option to the right of the command prompt icon (the partition tool) - it will ask you if it can sync the Mac boot table with the Win boot table (something like adding the MBR to the boot schedule) - say yes. It takes less than a second.
14 - Restart - and again hold option. Grab your original Windows installation CD and boot into it. Select your region and then go to "Repair your computer". Ignore the message about being able to fix and restart (choose No). Then choose Startup Repair. It'll do its thing. You can then restart.
